Carl Djerassi (91),a Stanford chemist broadly considered the father of the birth control pill, has died.
Djerassi was a key contributor to the invention of the birth control pill.
Later in his career, he turned to writing novels on mixing science and literature, and he considered himself a chemist, writer, teacher and philanthropist.
As reports say, Djerrasi died of entanglements of cancer in his San Francisco home.
Carl Djerassi is survived by a son, Dale Djerassi; a stepdaughter, Leah Middlebrook; and a grandson, Alexander M. Djerassi.
