Prolific playwright August Wilson, whose cycle of 10 plays chronicling the black experience in 20th-century America included such landmark dramas as Fences and Ma Rainey's Black Bottom, died on Sunday of liver cancer. He was 60. "We've lost... the greatest writer that our generation has seen," Kenny Leon, who directed Wilson's Gem of the Ocean and Radio Golf, his most recent play, tells the Associated Press. Wilson earned seven Tony nods (winning once for Fences), received a pair of Pulitzer Prizes and took home seven New York Drama Critics' Circle awards.
