About the Holiday

Gender equality around the world has always been a core issue for the United Nations. As such, on December 22, 2015 the United Nations General Assembly established an International Day to recognize the critical role women and girls play in science and technology. This year’s theme is “Equity, Diversity, and Inclusion: Water Unites Us.” As described in UN reports, by 2030 “billions of people around the world will be unable to access safely managed household drinking water, sanitation, and hygiene services unless access progress rates quadruple. Rising demand, poor management, and failure to conserve water resources, compounded by climate change, represent key challenges, urgently requiring a new sustainable holistic approach to support aligning strategies on water.”

Today’s celebration will bring together women in science and experts from around the world and government officials as well as representatives of international organizations and the private sector to discuss the importance of water in achieving the three pillars of sustainable development – economic prosperity, social justice, and environmental integrity. The program will also feature, for the first time, a unique Ebru Water Art Performance to celebrate the 7th Anniversary of the #February11 Global Movement. To access the virtual assembly, visit womeninscienceday.org. To learn more about today’s initiative as well as videos about past observances, visit the UN website

Code Breaker, Spy Hunter: How Elizebeth Friedman Changed the Course of Two World Wars

Written by Laurie Wallmark | Illustrated by Brooke Smart

 

In Code Breaker, Spy Hunter, readers open the cover to an intriguing question: “Could it be? Had enemy spies sneaked into the United States?” World War II was raging, but the United States had not yet joined the effort. And yet the “FBI had intercepted hundreds of coded messages from a secret base in New York.” The problem was no one could read them. Who did the FBI turn to? Elizebeth Smith Friedman, who broke the codes, discovered a cadre of Nazi spies, and provided the evidence “to send thirty-three German spies to prison.” Who was Elizebeth Friedman? Children are about to find out!

As a child, Elizebeth loved poetry and especially the work of William Shakespeare, with its structure and patterns. In college, she studied English literature, Latin, Greek, and German. While looking for a job in Chicago in 1916, she met the eccentric George Fabyan, who was trying to prove that Francis Bacon was the true writer of Shakespeare’s plays. He hired Elizebeth to “find secret messages Bacon had supposedly hidden in the plays. But the more she explored the plays, the more convinced she became that there were no hidden messages.”

Elizebeth shared her thoughts with a friend, William Friedman, who also loved puzzles and secret codes. Over a year’s time, their discussions resulted in a stronger friendship and finally marriage. In 1917, the US entered World War I and Fabyan asked Elizebeth and William to establish “the country’s first code-breaking unit, the Riverbank Department of Cyphers…. Their methods are now considered the basis for the modern science of cryptology, the study of secret codes.”

In 1921, Elizebeth and William moved to Washington D.C., where they worked as code breakers for the Army. At the time, the Army used a large, cumbersome machine to convert messages into code, which precluded soldiers in the field from sending intelligence back. Elizebeth and William invented a complex code that used “only pencil and paper.” After the war, Elizebeth settled down to write books and raise a family, but still the entreaties came to decode messages for court cases sometimes thousands of miles away.

In 1925 with Prohibition the law of the land, smugglers were running rampant. The Coast Guard summoned her, and within three months Elizebeth had cracked “two years of backlogged messages.” Her work and court testimony that helped to convict smugglers made Elizebeth a recognized expert in the new field of cryptology, and when the work became overwhelming for just two people, she created the Coast Guard’s first code-breaking unit.

With the entry of the US in World War II, Elizebeth’s expertise was once again needed. Again, she needed to create a code-breaking unit, and in 1942 she hired and taught “mathematicians, physicists, and chemists” the skills of cryptology. Now, Elizebeth’s team was learning important war information about the Nazi’s movements and plans. When the FBI director wanted to nab the spies, Elizebeth recommended waiting “until the military could learn more of the enemy’s secrets.” But he disagreed and raided their hiding place. The spies that escaped quickly changed their codes, making their communications harder to decipher. The FBI director took all the credit for breaking the codes and catching the spies.

As the war progressed, Elizebeth helped capture an American spy working for the Japanese, and when the Germans developed Enigma, a powerful code-making machine that could “create billions of different cipher alphabets, it was Elizebeth’s team that broke the code for the United States. In Allied countries around the world, other cryptologists were also decrypting Enigma messages. The Nazis were now at a disadvantage, their planned attacks thwarted. Historians believe the work of these code breakers “saved thousands of lives and shortened the war by many years.”

Throughout her life Elizebeth could not speak a word about her work, even to her family. It was classified as Top Secret Ultra by the government and kept locked in the National Archives. At last, in 2015, Elizebeth’s work was declassified. “She is now considered one of the most gifted and influential code breakers of all time.”

Compelling and wonderfully detailed, Laurie Wallmark’s biography of Elizebeth Friedman immerses children in the world of war-time spies, where cracking codes equaled saved lives and battles won. Wallmark’s storytelling of Elizabeth’s trajectory from Shakespeare scholar to ultra-secret code cracker reads like a thriller and is sprinkled throughout with quotes from Elizebeth that give kids a sense of her personality and the demands of her career. By including several cases Elizebeth was instrumental in solving, Wallmark provides readers with historical context on the broad range of nefarious activity that relied on secret codes to inform their knowledge of today’s uses of encryption as well as international spy networks. Each page is a celebration of Elizebeth’s talent, intelligence, and accomplishments, and her incredible story will enthrall readers.

Brooke Smart’s watercolor and gouache illustrations offer enticing glimpses into the past while following Elizebeth as she meets George Fabyon who shows her around his museum-like house while carrying a small monkey on his shoulder, establishes the United States’ first code-breaking unit, testifies in court, and thwarts the Nazis’ war plans. Interspersed with Smart’s realistic depictions of Elizebeth’s life are images in which lines of coded messages snake across the page, giving readers a look at the kinds of unreadable text Elizebeth and her teams cracked. In addition to presenting a visual representation of the tangled communications that eventually nabbed our enemies, two of these clever illustrations contain messages of their own.

A superlative biography that would enhance any history, social studies, language arts, or STEM curriculum as well as captivate kids who love spy, military, and detective stories, Code Breaker, Spy Hunter: How Elizebeth Friedman Changed the Course of Two World Wars is highly recommended for home bookshelves and is a must for school and library collections.

Picture Book Review

August 10 – Celebrating Inventors Month with Laurie Wallmark

celebrate-picture-books-picture-book-review-Laurie Wallmark-headshot-Jeanne Balsam

Award-winning author Laurie Wallmark has written picture-book biographies of women in STEM fields ranging from computer science to mathematics, astronomy to code breaking. Her books have earned multiple starred reviews, been chosen as Junior Library Guild Selections, and received awards such as Outstanding Science Trade Book, Cook Prize Honor, and Parents’; Choice Gold Medal. She is a former software engineer and computer science professor. She lives in Ringoes, New Jersey. (Photo credit Jeanne Balsam)

Thanks so much, Laurie, for stopping by to celebrate Inventors Month with me! Since this holiday recognizes innovators of the past and present, it seems a  perfect fit for your books that teach kids about amazing women whose inventions or inventive ways of thinking have changed our understanding of math, computers, communications, and even secret codes. 

Your love for these subjects and depth of research lead to compelling biographies. Reading them, I’ve often wondered whether a previous job has influenced your writing and the kinds of books you write. 

For many years I was a software engineer and, after that, a computer science professor. Not surprisingly, my first two women in STEM (science, technology, engineering, math) picture book biographies were about computer scientists, Ada Lovelace and Grace Hopper.  

The same love of math and science that led me to these careers also led me to want to encourage children’s interest in these fields. And what better way to do this than through books? I now have three more picture book biographies of women mathematicians and scientists out, the latest being Code Breaker, Spy Hunter: How Elizebeth Friedman Changed the Course of Two World Wars, with two more on the way.  

But it’s important not to fall into a rut in your writing, so my next title, coming out in October, is Dino Pajama Party. Because of my interest in STEM, people have asked me if it’s nonfiction. Um, no. But who knows? Maybe reading a fun, rhyming picture book about dinosaurs will encourage a child to grow up to be paleontologist. 

I’m sure readers are as thrilled as I am to hear that you have two more STEM-related books coming out! I’m really looking forward to seeing who they’re about! And what could be better than dinosaurs partying in pajamas?! What a terrific way to send little one’s off to bed.

Elizabeth’s career in code breaking began in an unusual way: through her love of Shakespeare. In 1916, she met the eccentric George Fabyan, who was trying to prove that Francis Bacon was the true writer of Shakespeare’s plays. He hired Elizebeth to “find secret messages Bacon had supposedly hidden in the plays. But the more she explored the plays, the more convinced she became that there were no hidden messages.” In 1917, with the US involved in World War I, Fabyan asked Elizebeth and her now-husband William Friedman, who was also an expert at secret codes, to establish “the country’s first code-breaking unit, the Riverbank Department of Cyphers….”

In 1921, they helped soldiers send sensitive intelligence from the field by devising a complex code that would use only pencil and paper instead of the Army’s cumbersome machine. During Prohibition, they helped stop smugglers and Elizabeth created the Coast Guard’s first code-breaking unit. With America’s entry into World War II, it was Elizabeth who figured out how to defeat the Germans’ powerful code-making machine, Enigma, which “saved thousands of lives and shortened the war by many years.”

About the Holiday

Are you an artist, a writer, a decorator, a chef? How about a floral arranger, a woodworker, a fashion designer, or a gardener? Inside almost every heart lies a desire to create. Whether you use your ingenuity in your job or as an escape from the routine, this month celebrates all that is innovative. Sometimes this comes not only in making something you can see or touch but in a new thought or a novel way of solving a problem—as seen in today’s book!

I received a copy of Hedy Lamarr’s Double Life for review consideration. All opinions are my own.

Hedy Lamarr’s Double Life: Hollywood Legend and Brilliant Inventor

Written by Laurie Wallmark | Illustrated by Katy Wu

 

In 1938 people were lining up to see Hedy Lamarr in her first English-language movie Algiers. Hedy was the talk of Hollywood, and journalists and photographers captured her every move—almost. What movie-goers and the press didn’t know was that Hedy Lamarr was also a brilliant inventor. Instead of attending fancy celebrity parties, after a long day on the set, “Hedy hurried home to work on her latest invention. Her brain overflowed with idea after idea for useful inventions.” While she never tried to sell her ideas—like the collar to help find lost pets or the “flavor cube that changed plain water into soda”—she designed and redesigned them to perfection.

celebrate-picture-books-picture-book-review-hedy-lamarr's-double-life-magazines

But how did Hedy get her start? She was born in Austria and as a child took apart mechanical objects just to see how they worked. Hedy’s father also loved science, and he encouraged his daughter to hold onto her dreams. In addition to science, Hedy loved movies and would use her dolls to reenact the scenes she saw.

When she got older, Hedy got a job as a script girl and then worked as an extra in a movie. She loved acting and once said, “‘I acted all the time…. I was a little living copybook. I wrote people down on me.’” While playing the lead in a stage play, the Hollywood producer Louis B. Mayer saw her and offered her movie contract. Hedy moved to America. It only took her six months to land a starring role in Algiers. After that she starred in many movies with some of the most famous actors and actresses. 

By now, the world was at war. One day, Hedy met George Antheil, a former weapons inspector who now composed music. Hedy remembered a “discussion she had overheard back in Europe about a problem with the guidance system for torpedoes. The guidance system couldn’t prevent the enemy from jamming the weapon’s radio signals” and sending it off course. She learned from George Antheil that the US Navy had the same problem.

They decided to team up to see if they could figure out a solution. Hedy was also an accomplished pianist, and she and George often played musical games on the piano. Once, while they played the same song in different octaves, Hedy had a brainstorm for building “a secure torpedo guidance system.” At the time, torpedo guidance systems only worked if the ship launching a torpedo and the torpedo were on the same frequency.

celebrate-picture-books-picture-book-review-hedy-lamarr's-double-life-home

Image copyright Katy Wu, 2019, text copyright Laurie Wallmark, 2019. Courtesy of Sterling Children’s Books.

Hedy thought that if the ship and the torpedo could switch between a series of different frequencies, the enemy would be foiled. “Hedy called her discovery ‘the hopping of frequencies.” Working together, she and George devised a way to implement Hedy’s idea. When they presented their idea to the National Inventors Council, they were told the “idea had ‘great potential value.’”

There were still some issues to overcome to make the system automated, but Hedy and George answered those too. They applied for a patent, and a year later on August 11, 1942 it was granted. When they gave the idea to the United States Navy, “Hedy was proud her frequency-hopping idea might help America win the war.” But embroiled in the middle of the conflict, the Navy didn’t have “the time or money to implement a new system….”

Hedy, who still wanted to help America defeat the Nazis, was undaunted. She helped raise 25 million dollars by selling war bonds and volunteered at the Hollywood Canteen, where servicemen soon to be deployed gathered. Hedy went on to make more than twenty movies and continued to work on her inventions.

In the 1980s, the US Navy declassified Hedy’s frequency-hopping technology, meaning anyone could use it. Because the patent had long-ago expired, no one needed to give Hedy and George credit for the idea. “Companies raced to include frequency hopping in their own devices.” In 1997, Hedy and George were finally recognized when they “received the Pioneer Award from the Electronic Frontier Foundation for their significant contribution to computers.”

A timeline of Hedy Lamarr’s life, a description of how Hedy and George’s frequency-hopping technology worked, additional resources for further reading, and a list of Hedy’s movies follow the text.

Laurie Wallmark knows how to weave a riveting tale that draws readers in to the lives of fascinating and scientifically minded women throughout history. Her detailed biography of Hedy Lamarr will wow kids with the twists and turns of how a vital feature of the electronics they use every day came to be. A history not only of this famous woman but of the times and policies that denied Hedy Lamarr the recognition and profits she deserved, the story is sure to spark plenty of discussion. The inclusion of a few of Hedy’s ingenious ideas as well as quotes on acting, inventing, and her views on life give children a glimpse into the mind of this unique woman.

Katy Wu takes readers back to the 1940s with her stylish illustrations reminiscent of magazine images of the time that depict both Hedy’s glamourous and inventive sides. Even as Hedy steps out of a limo to the glare of flashbulbs, acts under stage lights, and watches movies thrown by a projector’s beam, she’s dreaming of going home to work on her inventions in the light of a desk lamp. When the story turns to Hedy’s frequency-hopping idea, Wu clearly portrays the problems with the torpedo guidance system and the way single-frequency and multiple-frequency communications work. The way player pianos were controlled and how Hedy and George Antheil used this idea is also well portrayed. The final images of people using Hedy’s technology today lets kids fully understand the impact that Hedy Lamarr has had on their lives.

An important story about an extraordinary woman, Hedy Lamarr’s Double Life: Hollywood Legend and Brilliant Inventor will inspire children to follow and accomplish all of their dreams. The book will spur creative thought across subject matter and would be a motivational addition to home, classroom, and public libraries.

Picture Book Review

March 14 – It’s National Women’s History Month

celebrate-picture-books-picture-book-review-hedy-lamarr's-double-life-cover

About the Holiday

National Woman’s History Month was established by the United States Congress in 1987 to recognize and celebrate the achievements of American women in the past and today. This year’s theme is “Balance for Better,” which encourages true gender equity in the workplace, in government, and at home. Only when all people are heard and treated equally will communities thrive. There’s no better time than now to get involved to ensure that all have the same rights and standing in all areas of their lives.

I received a copy of Hedy Lamarr’s Double Life for review consideration. All opinions are my own. I’m excited to be partnering with Sterling in a giveaway of the book. See details below.

Hedy Lamarr’s Double Life: Hollywood Legend and Brilliant Inventor

Written by Laurie Wallmark | Illustrated by Katy Wu

 

In 1938 people were lining up to see Hedy Lamarr in her first English-language movie Algiers. Hedy was the talk of Hollywood, and journalists and photographers captured her every move—almost. What movie-goers and the press didn’t know was that Hedy Lamarr was also a brilliant inventor. Instead of attending fancy celebrity parties, after a long day on the set, “Hedy hurried home to work on her latest invention. Her brain overflowed with idea after idea for useful inventions.” While she never tried to sell her ideas—like the collar to help find lost pets or the “flavor cube that changed plain water into soda”—she designed and redesigned them to perfection.

celebrate-picture-books-picture-book-review-hedy-lamarr's-double-life-magazines

But how did Hedy get her start? She was born in Austria and as a child took apart mechanical objects just to see how they worked. Hedy’s father also loved science, and he encouraged his daughter to hold onto her dreams. In addition to science, Hedy loved movies and would use her dolls to reenact the scenes she saw.

When she got older, Hedy got a job as a script girl and then worked as an extra in a movie. She loved acting and once said, “‘I acted all the time…. I was a little living copybook. I wrote people down on me.’” While playing the lead in a stage play, the Hollywood producer Louis B. Mayer saw her and offered her movie contract. Hedy moved to America. It only took her six months to land a starring role in Algiers. After that she starred in many movies with some of the most famous actors and actresses. 

By now, the world was at war. One day, Hedy met George Antheil, a former weapons inspector who now composed music. Hedy remembered a “discussion she had overheard back in Europe about a problem with the guidance system for torpedoes. The guidance system couldn’t prevent the enemy from jamming the weapon’s radio signals” and sending it off course. She learned from George Antheil that the US Navy had the same problem.

They decided to team up to see if they could figure out a solution. Hedy was also an accomplished pianist, and she and George often played musical games on the piano. Once, while they played the same song in different octaves, Hedy had a brainstorm for building “a secure torpedo guidance system.” At the time, torpedo guidance systems only worked if the ship launching a torpedo and the torpedo were on the same frequency.

celebrate-picture-books-picture-book-review-hedy-lamarr's-double-life-home

Hedy thought that if the ship and the torpedo could switch between a series of different frequencies, the enemy would be foiled. “Hedy called her discovery ‘the hopping of frequencies.” Working together, she and George devised a way to implement Hedy’s idea. When they presented their idea to the National Inventors Council, they were told the “idea had ‘great potential value.’”

There were still some issues to overcome to make the system automated, but Hedy and George answered those too. They applied for a patent, and a year later on August 11, 1942 it was granted. When they gave the idea to the United States Navy, “Hedy was proud her frequency-hopping idea might help America win the war.” But embroiled in the middle of the conflict, the Navy didn’t have “the time or money to implement a new system….”

Hedy, who still wanted to help America defeat the Nazis, was undaunted. She helped raise 25 million dollars by selling war bonds and volunteered at the Hollywood Canteen, where servicemen soon to be deployed gathered. Hedy went on to make more than twenty movies and continued to work on her inventions.

In the 1980s, the US Navy declassified Hedy’s frequency-hopping technology, meaning anyone could use it. Because the patent had long-ago expired, no one needed to give Hedy and George credit for the idea. “Companies raced to include frequency hopping in their own devices.” In 1997, Hedy and George were finally recognized when they “received the Pioneer Award from the Electronic Frontier Foundation for their significant contribution to computers.”

A timeline of Hedy Lamarr’s life, a description of how Hedy and George’s frequency-hopping technology worked, additional resources for further reading, and a list of Hedy’s movies follow the text.

Laurie Wallmark knows how to weave a riveting tale that draws readers in to the lives of fascinating and scientifically minded women throughout history. Her detailed biography of Hedy Lamarr will wow kids with the twists and turns of how a vital feature of the electronics they use every day came to be. A history not only of this famous woman but of the times and policies that denied Hedy Lamarr the recognition and profits she deserved, the story is sure to spark plenty of discussion. The inclusion of a few of Hedy’s ingenious ideas as well as quotes on acting, inventing, and her views on life give children a glimpse into the mind of this unique woman.

Katy Wu takes readers back to the 1940s with her stylish illustrations reminiscent of magazine images of the time that depict both Hedy’s glamourous and inventive sides.

Grace Hopper: Queen of Computer Code

Written by Laurie Wallmark | Illustrated by Katy Wu

 

As Grace Hopper finished writing a computer code to guide Navy missiles, she noticed that there was a certain string of code that she had repeated many times. “Grace snorted. What a colossal waste of time! There had to be a better way. Why not make the computer do the work?” Grace figured out a way for the computer to store pieces of a program and then find them again to create another program. Grace was the first computer programmer to do this.

celebrate-picture-books-picture-book-review-grace-hopper-queen-of-computer-code-desk

Even as a child Grace loved to tinker with mechanical things. She once opened all the clocks in the house to figure out how they worked. What did her mother say when she saw that? “…all she could do was laugh. After all, Grace was just being Grace.” Later, she built an electric elevator for her dollhouse. She reveled in difficult problems, and while the girls in her class “wore frilly dresses and learned to be young ladies, Grace studies math and science.”

Studying hard, Grace finished high school two years early, and while she had the grades in math and science to go to college, she failed Latin. Without passing Latin, she couldn’t go to college. Grace buckled down and the next year she was off to Vassar College. Grace passed up taking classes such as “Husbands and Wives” and “Motherhood” to take math and physics. But Grace did a lot more than just study. “Her personal motto was ‘Dare and Do,’ and she took it to heart. She flew in a barnstormer airplane.

celebrate-picture-books-picture-book-review-grace-hopper-queen-of-computer-code-clock

Grace went on to graduate school at Yale and then took a job teaching at Vassar. She knew how to make her classes fun and informative. At this time America was at war and needed mathematicians. She tried to join the Navy, but they told her she was too old and too thin. She kept asking, however, and after a year, the Navy agreed to let her join. She “was assigned to write programs for one of the first computers ever built, the Mark I. Only a few people had ever programmed before, so she had to learn how to do it on her own.”

celebrate-picture-books-picture-book-review-grace-hopper-queen-of-computer-code-bath

Then one day Grace learned that “the new computer, the Mark II, had stopped working.” Grace and her coworkers searched and searched for an error in the code, but they found none. Then Grace thought that maybe the problem wasn’t in the code but in the computer itself. They looked inside the huge machine for loose wires or electrical shorts. Nothing. Then they saw it—a moth had gotten inside and was blocking a switch.

celebrate-picture-books-picture-book-review-grace-hopper-queen-of-computer-code-computer

Image copyright Katy Wu, 2017, text copyright Laurie Wallmark, 2017. Courtesy of Sterling Children’s Books.

With a tweezer, a worker removed the moth and the computer started up again. Grace taped the moth into the log book and wrote, “‘First actual case of [a computer] bug being found,’” and the term “computer bug” was born. Grace also revolutionized programming when she “invented a program that let people use words to tell the computer what to do” instead of pages and pages of 1s and 0s.

When Grace turned sixty, the Navy made her retire. Within six months, they asked her to return and she worked for them for another twenty years. She retired again at the age of eighty as the Queen of Computer Code. As many people called her, she really was “Amazing Grace.”

A timeline of Grace Hopper’s life as well as a list of honors awarded her and resources for further reading about Grace and other women in STEM.

Laurie Wallmark’s engaging biography of Grace Hopper will delight kids as they see her grow from a precocious and innovative child to a woman who used her intelligence and imagination to lead the computer revolution. Specific examples of Grace’s successes and the support she received at home will encourage other engineering-minded kids, and the inclusion of her failure in Latin demonstrates that everyone has areas of weakness that can be overcome with hard work. Grace’s perseverance in getting the Navy to accept her is also a good lesson for children on not giving up on their dreams. The provenance of the term “computer bug” will surprise and amuse readers.

Katy Wu’s charming illustrations of events in Grace Hopper’s life take readers back to time when computers were new. Children will marvel over the size and design of early computers. Grace’s sense of adventure and humor are on display is colorful and action-packed images. Uplifting and encouraging sayings by Grace Hopper that will inspire children are sprinkled throughout the pages.

A book to motivate children to reach for their dreams and spark pride in individual accomplishment, Grace Hopper: Queen of Computer Code would be an influential book to add to home, school, and public libraries.

October 11 – Ada Lovelace Day

celebrate-picture-books-picture-book-review-ada-byron-lovelace-and-the-thinking-machine-cover

About the Holiday

Today we remember the woman who is regarded as “the first computer programmer.” A mathematician, inventor, and scientific pioneer, Ada Lovelace wrote and was the first to publish an algorithm to generate Bernoulli numbers. Her notes published in Taylor’s Scientific Memoirs in 1842 inspired Alan Turing to design the first modern computers 100 years later. Today’s holiday celebrates all women in the science, technology, mathematics, and engineering fields. To learn more about Ada Lovelace Day visit findingada.com.

Ada Byron Lovelace and the Thinking Machine

Written by Laurie Wallmark | Illustrated by April Chu

 

Ada was the daughter of two very distinguished—and distinct—parents. Her mother loved geometry and was known as “‘The Princess of Parallelograms.’” Her father was a world-renowned poet, “beloved for his Romanic poems.” When Ada was still a baby, however, her mother left Lord Byron and his “scandalous behavior” behind, and “Ada never saw her father again.”

celebrate-picture-books-picture-book-review-ada-byron-lovelace-and-the-thinking-machine-ada's-parents

Image copyright April Chu, text copyright Laurie Wallmark. Courtesy of crestonbooks.com

As was common in Ada’s time she was often left on her own while her mother traveled. Ada filled the hours and days writing, sketching, and inventing in her journal. When she was still a little girl, she built a set of wings for a flying machine she had imagined. To discover if her wings could actually fly, “Ada needed to compute the wings’ power. She broke the problem into steps—surface area and weight, wind speed and angles.” She had to multiply and divide again and again, and while she loved calculating numbers, Ada wondered if there wasn’t an easier way to find the answers.

As she sat at her desk one day a storm blew up, sending the curtains around her open window flapping. They reminded Ada of sails and she suddenly realized that sails were like wings. She grabbed her toy sailboat and headed out to a nearby pond to test her theories. She launched her boat over and over, and “each time she adjusted the sails and studied the effect on the little boat’s speed. A storm of numbers and calculations whirled in her mind and spilled onto her pages.” She stayed by the pond until dark, and “returned home muddy, dripping wet, and triumphant.” Her nanny was not pleased. She didn’t agree with Ada’s mother, instead believing that girls “should not waste their time with math and science and experiments and other such nonsense.”

celebrate-picture-books-picture-book-review-ada-byron-lovelace-and-the-thinking-machine-imagining-a-flying-machine

Image copyright April Chu, courtesy of aprilchu.com

Overnight, Ada developed a high fever, and the doctor diagnosed measles. Ada’s mother was sent for. She hurried home and spent the days and nights at Ada’s bedside reading to her. Ada’s “fever finally broke, but the measles left her paralyzed and blind. To keep Ada’s mind sharp, Mama quizzed her on math problems,” asking her harder and harder questions. The numbers kept her company, and in her imagination Ada used her flying machine to travel to London.

While Ada regained her sight in a few weeks, it was three years before she could walk again. During this time Ada’s mother hired tutors to teach her higher and higher level math. One of her tutors was Mary Fairfax Somerville, a famous scientist and mathematician. Somerville invited Ada and her mother to a gathering of other influential scientists, mathematicians, and inventors. There Ada met Charles Babbage. Babbage, a mathematician and inventor, was impressed by 17-year-old Ada’s knowledge and understanding and invited her to visit his laboratory.

celebrate-picture-books-picture-book-review-ada-byron-lovelace-and-the-thinking-machine-difference-engine

Image copyright April Chu, courtesy of aprilchu.com

Ada brought her journal and shared with Charles Babbage her own work. He didn’t treat Ada as a child but as a fellow scientist and engineer. Babbage showed Ada a mechanical calculator he had designed. With the turn of a handle cylinders of numbers on the three columns of his Difference Engine spun toward the answer to a math problem Ada posed: what is 15 x 12? The machine gave the right answer: 180!

Babbage also had an idea for a mechanical computer—and Analytical Engine—that “would solve harder problems by working through them step by step.” It was an amazing concept, but Babbage hadn’t built it yet. He gave Ada his notebooks and she studied Babbage’s descriptions of how the machine might work. She realized that the Analytical Engine could work if numbers told it how.

celebrate-picture-books-picture-book-review-ada-byron-lovelace-and-the-thinking-machine-calculating

Image copyright April Chu, courtesy of aprilchu.com

Over several months Ada created an algorithm—a set of mathematical instructions. Her journal was filled with lines and lines of numbers and symbols. At last she checked her work for errors and found none. Ada had developed the world’s first computer program! With her creative imagination she could see that someday computers would “design powerful flying machines and majestic sailing ships. They would draw pictures and compose music. And they would play games and help with schoolwork.”

Unfortunately, Charles Babbage never finished building his Analytical Machine, and Ada never saw her program in action. But future generations remembered her and her contributions to computer programming. There is even a computer program named for her. We can imagine that the little girl who wanted to fly would be very pleased to know that Ada helps guide modern flying machines.

An extensive Author’s Note, a timeline of Ada’s life as well as a partial bibliography and resources follow the text.

celebrate-picture-books-picture-book-review-ada-byron-lovelace-and-the-thinking-machine-looking-at-stars

Image copyright April Chu, text copyright Laurie Wallmark. Courtesy of crestonbooks.com

Laurie Wallmark’s compelling biography of Ada Lovelace is perfectly aimed at her young audience, highlighting Ada’s childhood dreams, obstacles, and events that led her to become an influential mathematician and inventor. Wallmark’s fast-paced text, which beautifully merges lyrical and technical language to tell Ada’s story, is uplifting in its revelation that from even a young age, Ada was respected and acknowledged for her intelligence and mathematical gifts. Illuminating Ada’s predictions for future uses of the computer forms a bridge between her foresight and the experience of today’s children, bringing history alive for readers.

Gorgeous, detailed illustrations set Ada Byron Lovelace and the Thinking Machine firmly in its 19th-century time period. Lush greens, reds, and golds welcome readers into Ada’s home, where her wooden and paper wings lay among blueprints for other inventions as Ada sits at her desk jotting notes in her journal. A mural in her home cleverly depicts Ada’s imaginings while she recovered from the measles, and the gathering that Ada and her mother attend is a stimulating portrait of the scientists and new inventions of the day. Kids will be amazed to see one of the first “calculators” as built by Charles Babbage. Included on the pages are images of an early loom and punch cards that influenced the development of our computers. It is fitting that the last page shows how far we have come—and how forward thinking Ada was—with an illustration of Space technology in action.

Ada Byron Lovelace and the Thinking Machine is an important biography that should be included in every public and school library. For children interested in history, biographies, and the science and math fields, Laurie Wallmark’s and April Chu’s book would make a beautiful gift and addition to home bookshelves as well.
