Actor Robert Mandan has appeared in several hit television shows over the years, but he'll forever be best-known as the devious but ultimately good-hearted millionaire Chester Tate on the soap opera parody "Soap. " Mandan first began acting professionally during the early 1960s, with stints on quickly-forgotten television shows like "From These Roots" and "Jackie Gleason and His American Scene Magazine." But by the middle of the decade, he had landed his breakout role as businessman Sam Reynolds on the soap opera "Search for Tomorrow." After leaving the show in 1970, Mandan would spend several years landing small roles on such popular shows as the controversial social satire "All in the Family" and the gritty crime drama "Kojak," before taking on the key role as Chester Tate on "Soap" in 1977. After "Soap" left the air in 1981, Mandan played opposite John Ritter on the short-lived "Three's Company" spinoff "Three's a Crowd."
