Ken Cosgrove is an Account Executive at the Sterling Cooper advertising agency who spends much of his time at work with Pete Campbell, Paul Kinsey, and Harry Crane. A bachelor who likes to flirt, Ken has written two unpublished novels and became the target of office jealousy when his short story, "Tapping a Maple on a Cold Vermont Morning," was published in the Atlantic Monthly. Though he made frequent jokes about Peggy Olson’s weight gain (during her unwitting pregnancy), he was supportive of her copywriting efforts and successes.
