Susan Keating Glaspell (1876 - 1948) was an American playwright, novelist, journalist and actress. With her husband George Cram Cook, she founded the Provincetown Players, the first modern American theatre company.
First known for her short stories (fifty were published), Glaspell is known also to have written nine novels, fifteen plays, and a biography. Often set in her native Midwest, these semi-autobiographical tales typically explore contemporary social issues, such as gender, ethics, and dissent, while featuring deep, sympathetic characters who make principled stands. Her 1930 play Alison's House earned her the Pulitzer Prize for Drama.
