A Rat's Mass: "A Rat's Mass" is a poetic, magical-realist one act written by Adrienne Kennedy, an African-American playwright whose work was made in the 20th century.

Louis S. Peterson: Louis S. Peterson (June 17, 1922 – April 27, 1998) was a playwright, actor, screenwriter, and professor.  He was an American playwright and the first African-American playwright to have a dramatic play produced on Broadway.

Kathleen Collins: Kathleen Collins (March 18, 1942 – September 18, 1988) (also known as Kathleen Conwell, Kathleen Conwell Collins or Kathleen Collins Prettyman) was an African-American playwright, writer, filmmaker, director, civil rights activist, and educator from Jersey City, New Jersey.  Her two feature narratives—"The Cruz Brothers and Miss Malloy" (1980) and "Losing Ground" (1982)—furthered the range of Black women's films.  Although "Losing Ground" was denied large-scale exhibition, it was among the first films created by a Black woman deliberately designed to tell a story intended for popular consumption, with a feature-length narrative structure.  Collins thus paved the way for Julie Dash's "Daughters of the Dust" (1991) to become the first feature-length narrative film created by a Black woman to be placed in commercial distribution.  Influenced by Lorraine Hansberry, she wrote about "African Americans as human subjects and not as mere race subjects" [emphasis in the original].
