David Steinberg (born August 9, 1942) is a Canadian comedian, actor, writer, director, and author. At the height of his popularity, during the late 1960s and mid 1970s, he was one of the best-known comics in the United States. He appeared on The Tonight Show Starring Johnny Carson more than 130 times (second only to Bob Hope in number of appearances) and served as guest host 12 times, the youngest person ever to guest-host. Steinberg directed several films and episodes of television situation comedies, including Seinfeld, Friends, Mad About You, Curb Your Enthusiasm, The Golden Girls, and Designing Women. Since 2012, Steinberg has hosted the interview program Inside Comedy on the Showtime network. Early life Steinberg was born on August 9, 1942 in Winnipeg, Manitoba, Canada. He is the son of Rabbi Yasha Steinberg (1896-1966), a strict, Romanian-born rabbi, and Ruth Steinberg (circa 1904-1989).
