Alice Walker is profiled on 'American Masters' on PBS.

The PBS television series "American Masters" will debut its profile of Alice Walker on Feb. 7, shortly before the author's 70th birthday.

While Walker has written novels, poetry and nonfiction, she is best known for her novel "The Color Purple." Published in 1983, it won both the Pulitzer Prize and the National Book Award, and was made into the film directed by Steven Spielberg.

Danny Glover, one of the stars of that film, appears in the documentary about Walker and its preview, above.

"American Masters" profiles significant American figures in the arts, sports, and popular culture. Walker joins fellow writers J.D. Salinger, James Baldwin and Philip Roth this season alongside Billie Jean King, David Geffen, Marvin Hamlisch and Jimi Hendrix.
