Born November 20, 1942 in Los Angeles, California, Bob Einstein is the son of actress Thelma Leeds and radio comedian Harry "Parkyakarkus" Einstein. His older brother, Clifford, is an advertising executive, and his younger brother, Albert is better known as Albert Brooks.
One of Einstein's earliest jobs was writing for The Smothers Brothers Comedy Hour, for which he and the other writers (including Rob Reiner and Steve Martin) earned an Emmy. He also created the character of "Officer Judy" on the show, as well as many others. After CBS pulled the show off the air, he continued to make guest appearances on television, and was seen regularly on The Steve Allen Show, The Tonight Show with Johnny Carson and Late Night with David Letterman, among many others.
By the start of the 1970s, Bob's career as a writer and producer was in full swing, with credits including The Sonny and Cher Comedy Hour, The Redd Foxx Comedy Hour, and Van Dyke and Company (for which he won his second Emmy). Einstein would occasionally appear on these shows as a performer. His success in television continued into the 1980s with Bizarre (which starred John Byner), and Super Dave, for which he won a CableACE award for Best Actor in a Comedy Series. In both of the latter series, he appeared as his most well-known character, hapless stunt man Super Dave Osborne.
Einstein's film appearances have been as eclectic as the rest of his career. In 1972, he had a small role in Get to Know Your Rabbit (with Tom Smothers), and, later that year, made his film debut as a writer/director with Another Nice Mess, which starred Rich Little, and was produced by Tom Smothers. In 1981, he was seen in brother Albert Brooks' film Modern Romance, which also featured performances by his mother, and his brother Clifford. He also appeared in Harry Shearer's film Teddy Bears' Picnic and was seen as himself in the documentary Smothered: The Censorship Struggles of The Smothers Brothers Comedy Hour. More recently, he appeared as FBI agent Robert Caldwell in Ocean's 13 (with George Clooney and Brad Pitt).
Einstein has continued to have a busy career as a character actor on television as well, with a list of TV credits including Curb Your Enthusiasm, Arrested Development, Crank Yankers, and Anger Management.
