Knight was born in Corinth, Miss., but grew up in Paducah, Ky. He enlisted in the U.S. Army in 1947, serving in the Korean War, but was discharged in 1950 after suffering shrapnel wounds. He moved to Indianapolis, where his family had relocated.
In 1960, Knight was convicted of drug-related armed robbery and spent eight years in prison. The back cover of his first poetry collection, Poems from Prison (1968), read: “I died in Korea from a shrapnel wound, and narcotics resurrected me. I died in 1960 from a prison sentence and poetry brought me back to life.”
During his career, which took him to cities including Pittsburgh and Memphis, Knight earned Pulitzer Prize and National Book Award nominations and fellowships and prizes from the Guggenheim Foundation and the National Endowment for the Arts. But he remained a community poet at heart.
Knight died in Indianapolis of lung cancer on March 10, 1991. Two months earlier, more than 700 people gathered at the American Cabaret Theatre to pay tribute to him. He is buried in Crown Hill Cemetery.
