Mark W. Moses (born February 24, 1958) is an American actor, known for his roles of Paul Young on Desperate Housewives and Herman "Duck" Phillips on the AMC series Mad Men. Moses was born in New York City, the brother of actor and singer Burke Moses. Moses grew up in Evanston, IL and was the quarterback for Evanston high school football. Moses has appeared in a number of films by director Oliver Stone, such as Platoon, The Doors, and Born on the Fourth of July. As a character actor with appearances on projects ranging as diverse as Big Momma's House 2 (2006), Platoon (1986) and Star Trek: Voyager (1999), Moses was always reliably employed, but never became a household name. This changed in 2004, when Moses was cast in the role of Paul Young on the hit ABC dramedy Desperate Housewives (2004–2007). As the disturbed husband of the deceased (suicide victim) Mary Alice Young, Moses played one of the pivotal figures in the show's original main mystery. He played Herman "Duck" Phillips on the AMC series Mad Men until 2009.
