Patrick Duffy is a television actor from Montana who became famous playing kind, "good guy" characters on hit TV shows.
Patrick Duffy was born in Townsend, Montana, on March 17, 1949, and grew up partly in a tiny Montana town and later in Washington state, where he got serious about drama and was accepted into a special professional acting program at the University of Washington. After college he struggled with odd jobs until he landed his first big TV part as the underwater hero Mark Harris in Man from Atlantis in 1977, and soon after became a worldwide star as the honest, younger brother Bobby Ewing on the prime-time drama Dallas, a role he played from 1978-1991 and again in a new Dallas series from 2012-2014. In the 1990s he starred as a funny, caring stepdad on the family sitcom Step by Step and later appeared on shows like The Bold and the Beautiful, guest-starred on Family Guy in a joke about his famous Dallas "shower scene," and has also directed many TV episodes. Duffy married ballet dancer Carlyn Rosser in 1974, they had two sons, and in recent years he has continued acting, made appearances at fan events, and launched a bread company called Duffy's Dough that donates profits to help fight hunger.
