Comer Vann Woodward was a Pulitzer-prize winning American historian focusing primarily on the American South and race relations. He was long a supporter of the approach of Charles A. Beard, stressing the influence of unseen economic motivations in politics. Stylistically, he was a master of irony and counterpoint. Woodward was on the left end of the history profession in the 1930s. By the 1950s he was a leading liberal and supporter of civil rights. His demonstration that racial segregation was a late-19th-century invention rather than some sort of eternal standard made his The Strange Career of Jim Crow into "the historical Bible of the civil rights movement", said Martin Luther King Jr. After attacks on him by the New Left in the late 1960s, he moved to the right politically.
