John Lewis

Lewis, who died July 17, grew up the son of sharecroppers. He later became an associate of Martin Luther King and co-led the 1965 civil rights march in Selma, Ala. Originally broadcast in 2009.

On March 7, 1965, marchers from Selma, Ala., attempted to cross a bridge to demonstrate in support of voting rights. Selma director Ava DuVernay, John Lewis and J.L. Chestnut reflect on that day.

In his regular feature "Interval," jazz critic Francis Davis explains the work of post-bop pianist John Lewis.
