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 1977 From 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.
