Howard Zinn was an American historian, playwright, philosopher, socialist intellectual and World War II veteran. He was chair of the history and social sciences department at Spelman College, and a political science professor at Boston University. Zinn wrote more than 20 books, including his best-selling and influential A People's History of the United States in 1980. In 2007, he published a version of it for younger readers, A Young People's History of the United States.

Zinn described himself as "something of an anarchist, something of a socialist. Maybe a democratic socialist." He wrote extensively about the civil rights movement, the anti-war movement and labor history of the United States. His memoir, You Can't Be Neutral on a Moving Train (Beacon Press, 1994), was also the title of a 2004 documentary about Zinn's life and work. Zinn died of a heart attack in 2010, at the age of 87.
