Johnathan Southworth “John” Ritter (September 17, 1948 – September 11, 2003) was an Emmy- and Golden Globe award-winning American actor and comedian perhaps best known for his role of Jack Tripper in the sitcom Three's Company.
Ritter was born in Burbank, California, the son of Dorothy Fay (née Southworth), an actress, and singing-cowboy, matinee-star Tex Ritter. He attended Hollywood High School, where he was Student Body President. He went on to the University of Southern California, where he was a member of the Phi Gamma Delta (FIJI) fraternity, majored in psychology and minored in architecture.
Ritter headlined several stage performances before he was made a star by appearing in the hit sitcom Three's Company (the Americanized version of the 1970s British Thames Television series Man About the House) in 1977, playing a single ladies' man and culinary student, Jack Tripper, who lived with two female roommates. Jack pretended to be gay to keep the landlords appeased over their living arrangement. The show spent several seasons near the top of the TV ratings in the U.S. before ending in 1984. Ritter went on for one more year on the spin-off Three's a Crowd. The original series has been seen continuously in reruns. It is also available on DVD. During the run of the show, he appeared in the feature films Hero at Large, Americathon, and They All Laughed. In 1978, he played Ringo Starr's manager on the television special Ringo, and in 1982, played the voice of Peter Dickinson in Flight of Dragons.
