Pat Morita, 73
Morita, born and raised in Northern California, was held in an interment camp as a youth during World War II, later went on to careers in the restaurant business and aerospace. He entered show business in the 30s, appearing in numerous television shows and sitcoms. In addition to his role on Happy Days as Arnold, Morita had a lesser known recurring role on that oh so LA-centric of sitcoms, Sanford and Son, as "Ah Chew" an Asian neighbor of Redd Foxx's Fred Sanford character.
Morita, whose given first name was Noriyuki, died Thursday of natural causes at his Las Vegas home. He leaves behind a wife and three daughters from a previous marriage.
