W.E.B Du Bois dedicated his life not only to racial justice but also to world peace.

Du Bois was an American sociologist, socialist, historian, and Pan-Africanist civil rights activist. Born in Great Barrington, Massachusetts, Du Bois grew up in a relatively tolerant and integrated community. After completing graduate work at the Friedrich Wilhelm University (in Berlin, Germany) and Harvard University, where he was the first African American to earn a doctorate, he became a professor of history, sociology, and economics at Atlanta University. Du Bois was one of the founders of the National Association for the Advancement of Colored People (NAACP) in 1909.

Du Bois was a prolific author. His collection of essays, The Souls of Black Folk, is a seminal work in African-American literature; and his 1935 magnum opus, Black Reconstruction in America, challenged the prevailing orthodoxy that blacks were responsible for the failures of the Reconstruction Era. Borrowing a phrase from Frederick Douglass, he popularized the use of the term color line to represent the injustice of the separate but equal doctrine prevalent in American social and political life. He opens The Souls of Black Folk with the central thesis of much of his life's work: "The problem of the twentieth century is the problem of the color-line."

His 1940 autobiography Dusk of Dawn is regarded in part as one of the first scientific treatises in the field of American sociology, and he published two other life stories, all three containing essays on sociology, politics and history. In his role as editor of the NAACP's journal The Crisis, he published many influential pieces. Du Bois believed that capitalism was a primary cause of racism, and he was generally sympathetic to socialist causes throughout his life. He was an ardent peace activist and advocated nuclear disarmament. The United States Civil Rights Act, embodying many of the reforms for which Du Bois had campaigned his entire life, was enacted a year after his death.
