Walker became a literature professor at what is today Jackson State University, an historically black college, where she taught from 1949 to 1979. In 1968, Walker founded the Institute for the Study of History, Life, and Culture of Black People and her personal papers are now stored there. In 1976, she went on to serve as the Institute's director.
Literary writing
In 1942, Walker's poetry collection For My People won the Yale Series of Younger Poets Competition under the judgeship of editor Stephen Vincent Benet, thus making her the first black woman to receive a national writing prize. Her For My People was considered the "most important collection of poetry written by a participant in the Black Chicago Renaissance before Gwendolyn Brooks's A Street in Bronzeville." Richard Barksdale says: "The poem was written when "world-wide pain, sorrow, and affliction were tangibly evident, and few could isolate the Black man's dilemma from humanity's dilemma during the depression years or during the war years." He said that the power of resilience presented in the poem is a hope Walker holds out not only to black people, but to all people, to "all the Adams and Eves." Walker's second published book, Jubilee, is the story of a slave family during and after the Civil War, and is based on her great-grandmother's life. It took her thirty years to write. Roger Whitlow says: "It serves especially well as a response to white 'nostalgia' fiction about the antebellum and Reconstruction South." This book is considered important in African-American literature and Walker is an influential figure for younger authors. She was the first of a generation of women who started publishing more novels in the 1970s. In 1975, Walker released three albums of poetry on Folkways Records – Margaret Walker Alexander Reads Poems of Paul Laurence Dunbar and James Weldon Johnson and Langston Hughes; Margaret Walker Reads Margaret Walker and Langston Hughes; and The Poetry of Margaret Walker. Walker received a Candace Award from the National Coalition of 100 Black Women in 1989.
Court cases
In 1978, Margaret Walker sued Alex Haley, claiming that his 1976 novel had violated Jubilee's copyright by borrowing from her novel. The case was dismissed. In 1991 Walker was sued by Ellen Wright, the widow of Richard Wright, on the grounds that Walker's use of unpublished letters and an unpublished journal in a just-published biography of Wright violated the widow's copyright. Wright v. Warner Books was dismissed by the district court, and this judgment was supported by the appeals court.
