Noted author Ellen Levine, whose books for young people were born of a love for teaching and her active espousal of social justice, died on May 26 of lung cancer. She was 73.

Her 2007 picture book Henry’s Freedom Box (Scholastic), illustrated by Kadir Nelson, was the true story of a slave named Henry “Box” Brown who mailed himself north to freedom in a wooden packing crate. The title received warm critical praise and was named a Caldecott Honor Book. Some of her other well-known publications include I Hate English! (Scholastic), Freedom’s Children: Young Civil Rights Activists Tell Their Stories (Putnam), and Rachel Carson: A Twentieth-Century Life (Viking). Levine published several nonfiction works for adults as well.

A woman of wide-ranging interests and talents, Levine earned degrees in politics and political science, was an attorney for a public-interest law group after receiving her law degree from New York University in 1979, and was a respected documentary filmmaker, woodcarver and freelance photographer. She also was an adult literacy and ESL tutor and taught courses in writing for children and young adults in Vermont College’s MFA program.

She is survived by her spouse and partner Anne Koedt, also an author and illustrator of children’s books, her sister and brother-in-law Mada Leibman and Burt Liebman, and nieces and nephews.
