    But in private, she was something more: a brilliant inventor. And for many years only her closest friends knew her secret. The story of how, during World War Two, Lamarr developed a groundbreaking communications system that still remains essential to the security of today’s technology.

    It was the first trip across an engineering marvel that had taken nearly fourteen years to construct. The woman's husband was the chief engineer, and he knew all about the dangerous new technique involved. The woman insisted she learn as well. When he fell ill mid-construction, her knowledge came in handy. She supervised every aspect of the project while he was bedridden, and she continued to learn about things only men were supposed to know:math,science,engineering.Women weren't supposed to be engineers. But this woman insisted she could do it all, and her hard work helped to create one of the most iconic landmarks in the world. This is the story of Emily Roebling, the secret engineer behind the Brooklyn Bridge, from author-illustrator Rachel Dougherty.

    She knew how many miles it was to the moon (and how many back). She loved studying algebra and geometry and calculus and using math to solve problems in the outside world.Soon math led her to MIT and then to helping NASA put a man on the moon! She handwrote code that would allow the spacecraft’s computer to solve any problems it might encounter. Apollo 8. Apollo 9. Apollo 10. Apollo 11. Without her code, none of those missions could have been completed.Dean Robbins and Lucy Knisley deliver a lovely portrayal of a pioneer in her field who never stopped reaching for the stars.

    Vera Rubin was one of the astronomers who discovered and named dark matter, the thing that keeps the universe hanging together. Throughout her career she was never taken seriously as a scientist because she was one of the only female astronomers at that time, but she didn’t let that stop her. She made groundbreaking and incredibly significant discoveries that scientists have only recently been able to really appreciate—and she changed the way that we look at the universe.

    Whir. Buzz.Not so long ago, math problems had to be solved with pencil and paper, mail delivered by postman, and files were stored in paper folders and metal cabinets. But three women, Betty Snyder, Jean Jennings, and Kay McNulty knew there could be a better way. During World War II, people hoped ENIAC (Electronic Numerical Integrator and Computer), one of the earliest computers, could help with the war effort. With little guidance, no instructions, and barely any access to the machine itself, Betty, Jean, and Kay used mathematics, electrical engineering, logic, and common sense to command a computer as large as a room and create the modern world. The machine was like Betty, requiring outside-the-box thinking, like Jean, persistent and consistent, and like Kay, no mistakes, every answer perfect. Today computers are all around us, performing every conceivable task, thanks, in large part, to Betty, Jean, and Kay's pioneering work. Instructions Not Included is their story.This fascinating chapter in history is brought to life with vivid prose by Tami Lewis Brown and Debbie Loren Dunn and with striking illustrations by Chelsea Beck. Detailed back matter including historical photos provides a closer look.

    Henrietta spent years measuring star positions and sizes from photographs taken by the telescope at the Harvard College Observatory, where she worked. After Henrietta observed that certain stars had a fixed pattern to their changes, her discovery made it possible for astronomers to measure greater and greater distances—leading to our present understanding of the vast size of the universe.An astronomer of her time called Henrietta Leavitt “one of the most important women ever to touch astronomy,” and another close associate said she had the “best mind at the Harvard Observatory.” Henrietta Leaveitt's story will inspire young women and aspiring scientists of all kinds and includes additional information about the solar system and astronomy.

    Back in the 1830s, who was a young blacksmith from Vermont, about to make his mark on American history? John Deere, that’s who!Who moved to Illinois, where farmers were struggling to plow through the thick, rich soil they called gumbo? Who tinkered and and tweaked and tested until he invented a steel plow that sliced into the prairie easy as you please?Long before the first tractor, who changed farming forever? John Deere, that’s who!Beautiful illustrations—including spectacular landscapes—reflect the time period and bring John Deere's remarkable story to life.

    Jane didn’t have much opportunity to go to school but she read everything she could, including the books in her father’s study. And before long, she began to write her own stories, filled with funny, clever, and inventive characters.Today, Austen’s novels ― including Pride and Prejudice, Sense and Sensibility, and Emma ― are widely read around the world. She's recognized as one of the most important and influential writers of all time; about her J.K. Rowling has said, "Jane Austen is the pinnacle to which all authors aspire."

    Growing up in New York in the late 1800s was not easy. When she lost her brother and father to typhoid fever, she became determined to pursue her dream of becoming a doctor. In Jo's day, medical schools were closed to women, but times were changing, and Jo was at the forefront.When she graduated in 1898, Dr. Jo still faced prejudice against women in her field. Not many people were willing to be seen by a female doctor, and Dr. Jo's waiting room remained mostly empty. She accepted a job in public health and was sent to Hell's Kitchen, one of New York's poorest neighborhoods where many immigrants lived. There, she was able to treat the most vulnerable patients: babies and children. She realized that the best treatment was to help babies get a stronger start in life. Babies need fresh air, clean and safe environments, and proper food. Dr. Jo's successes, fueled by her determination, compassion and ingenuity, made her famous across the nation for saving the lives of 90,000 inner city infants and children.

    Like her mother, she had a passion for science, math, and machines. It was a very good combination. Ada hoped that one day she could do something important with her creative and nimble mind.A hundred years before the dawn of the digital age, Ada Lovelace envisioned the computer-driven world we know today. And in demonstrating how the machine would be coded, she wrote the first computer program. She would go down in history as Ada Lovelace, the first computer programmer.Diane Stanley’s lyrical writing and Jessie Hartland’s vibrant illustrations capture the spirit of Ada Lovelace and bring her fascinating story vividly to life.

    The planet is full of millions of species of plants, birds, animals, and microbes, and every single one -- including us -- is part of a big, beautiful, complicated pattern. When humans interfere with parts of the pattern, by polluting the air and oceans, taking too much from the sea, and cutting down too many forests, animals and plants begin to disappear. What sort of world would it be if it went from having many types of living things to having just one? In a beautiful follow-up, the creators of the award-winning Tiny Creatures: The World of Microbes deliver an inspiring look at the extraordinary diversity of Earth's inhabitants -- and the importance of their preservation.

    For years before becoming a justice of the Supreme Court, Ruth had to fight the notion that being female meant that she was less smart, less qualified, and less worthy of attention than her male counterparts. Throughout college, law school, and her work life, she faced discrimination—because she was a woman.But it was in her fight for equality as a lawyer that she made an imprint on American history, by changing the way the law dealt with women's rights and by showing people that unfairness to women wasn’t just a female problem—that it negatively affected men and children, too.
