William Dwight Schultz (born November 24, 1947) is an American stage, television and film actor. He is best known for his roles as Captain "Howling Mad" Murdock on the 1980s action show The A-Team, Reginald Barclay in Star Trek: The Next Generation, Star Trek: Voyager, and the film Star Trek: First Contact and Mung Daal in the children's cartoon Chowder.
Schultz was born in Baltimore, Maryland. He is a graduate of Calvert Hall College High School and an alumnus of Towson University, both located in Towson, Maryland. He married former actress Wendy Fulton (Bare Essence) in 1983 and has a daughter named Ava, who graduated from the Virginia Military Institute in 2009.
Schultz' breakthrough role was the mentally unstable Captain "Howling Mad" Murdock on The A-Team. At the series outset, the producers felt that his character would be too over-the-top for viewers and planned to drop him after his debut, but early test screenings showed that he was popular with the audience. As a result, he was effectively "written back in" to the series.
