Gilda Susan Radner (June 28, 1946 – May 20, 1989) was an American comedienne and actress, best known for her five years as part of the original cast of the NBC comedy series Saturday Night Live, for which she won an Emmy Award. Radner's death at 42 of ovarian cancer helped increase public awareness of the disease and the need for earlier detection and treatment.

Radner was born in Detroit, Michigan, the daughter of Jewish parents Henrietta (née Dworkin), a legal secretary, and Herman Radner, a businessman. She grew up in Detroit with a nanny, Elizabeth Clementine Gillies, whom she called "Dibby" (and on whom she based her famous character Emily Litella), and an older brother named Michael. She attended the University Liggett School in Grosse Pointe.

Radner was close to her father, who operated Detroit's Seville Hotel, where many nightclub performers and actors stayed while performing in the city. Her father, who died when she was fourteen, took her on trips to New York to see Broadway shows.
