Wesley Lau was born and raised in Sheboygan, Wisconsin. A World War II veteran of the United States Army Air Corps, Lau studied playwriting at the University of Wisconsin and received a Master of Arts degree at Yale Drama School, later continuing his studies at The Actors Studio in New York.
He took time off from college at one point to serve in World War II as part of the air corps. Although his goal in life was to be a writer, he ended up acting simply because he found more jobs as an actor than as a playwright when he arrived in New York City seeking work.
Career
During his acting career, Lau was probably best known as Lt. Andy Anderson in the series Perry Mason. He appeared frequently during the latter part of the show's run, especially during times when longtime series regular Ray Collins, who played Lt. Arthur Tragg, was absent. (Collins died in 1965 before the series ended its run.) Lau first appeared on Perry Mason as defendant Amory Fallon in "The Case of the Impatient Partner" in September 1961. Less than a month later, he made the first of 81 appearances as Lt. Anderson, a role which ran from the fourth episode ("The Case of the Malicious Mariner") of the fifth season (1961–1962) through the last episode ("The Case of the Mischievous Doll") of the eighth season (1964–1965).
