A picture book biography celebrating the life and work of disability rights activist and icon Judith Heumann, highlighting one of her landmark achievements-leading the historic 504 Sit-in in 1977From a very young age, Judy Heumann heard the word NO. When she wanted to attend public school, the principal said, "NO." When she wanted her teaching license, the New York Board of Education said, "NO." Judy and people with disabilities everywhere were tired of hearing "NO."In the 1970s an important disability rights law, Section 504 of The Rehabilitation Act of 1973, was waiting to be signed. Judy and other disability rights activists fought for "YES!" They held a sit-in until Section 504 was signed into law. Section 504 laid the foundation for the Americans with Disabilities Act, which was established thanks in large part to the ongoing work of Judy and her community. Along with a personal reflection from Judy herself, this picture book biography captures the impact and influence of one of America's greatest living activists.

For fans of the "Who Was" series, this lively, accessible, and full-color chapter book biography shows how a self-taught scientist was the first to observe the microbial life in and around us. By building his own microscope, Antony van Leeuwenhoek advanced humanity's understanding of our oft-invisible world around us. Proving that remarkable discoveries can come from the most unexpected people and places, this eye-opening chapter book, illustrated with lively full-color art, celebrates the power of curiosity, ingenuity, and persistence. Microbes are everywhere: in the soil and oceans, in snow, and inside our bodies. But in Antony van Leeuwenhoek's time, people believed that what they saw with their own eyes was all that existed in the world. How did a simple tradesman-who didn't go to college or speak English or Latin like all the other scientists-change everyone's minds?

From the author of the National Jewish Book Award Finalist Bartali’s Bicycle comes the story of unsung hero Katalin Karikó, the scientist whose research of mRNA led to the world-altering development of the Covid-19 vaccine. Perfect for readers who love science, STEM, and books like Dr. Fauci: How a Boy from Brooklyn Became America’s Doctor or Hidden Figures: The True Story of Four Black Women and the Space Race. When she was young, Katalin Karikó decided she would study science—even though she had never even met a scientist! But she was determined to learn as much as she could about the human body, and once she made a decision, she stuck with it. Katalin had to learn English while attending university, but she worked hard until she became a doctor. After facing many challenges, including lack of research funding and harsh immigration policies, Kati and her family uprooted from Hungary and moved to America, where she became a top researcher. She knew that, with work, she could teach one of the building blocks of life, messenger RNA, to fight off harmful viruses. There was just one problem—no one else believed her. Then, the COVID-19 pandemic hit, and Kati and her work were thrust into the spotlight. But with her unshakable will, she was ready to face the challenge. Includes a note from Dr. Karikó, a time line, and more information about mRNA.
