Del Close (March 9, 1934 – March 4, 1999) was an American actor, writer, and teacher who coached many of the best-known comedians and comic actors of the late twentieth century. In addition to an acting career in television and film, he was one of the influences on modern improvisational theater. Close is co-founder of the iO, or iO Chicago, (formerly known as "ImprovOlympic"). Life and career Early life Close was born on March 9, 1934, in Manhattan, Kansas. He ran away from home at the age of 17 to work in a traveling side show, but returned to attend Kansas State University. At age 19 he performed in summer stock with the Belfry Players at Lake Geneva, Wisconsin. At age 23 he became a member of the Compass Players in St. Louis. When most of the cast—including Mike Nichols and Elaine May—moved to New York City, Close followed. He developed a stand-up comedy act, starred as the Yogi in the Broadway musical revue The Nervous Set, and performed briefly with an improv company in Greenwich Village with fellow Compass alumni Mark and Barbara Gordon. Close also worked with John Brent to record the classic Beatnik satire album How to Speak Hip, a parody of language-learning tools that purported to teach listeners the secret language of the "hipster". Chicago years In 1960 Close moved to Chicago, his home base for much of the rest of his life, to perform and direct at Second City, but was fired due to substance abuse. He spent the latter half of the 1960s in San Francisco where he was the house director of improv ensemble The Committee, featuring performers such as Gary Goodrow, Carl Gottlieb, Peter Bonerz, Howard Hesseman and Larry Hankin. He toured with the Merry Pranksters, and he created light images for Grateful Dead shows. In 1972, he returned to Chicago and to Second City. He also directed and performed for Second City's troupe in Toronto in 1977. Over the next decade he coached many popular comedians. In the early 1980s he served as "house metaphysician" at Saturday Night Live; for many years, a significant percentage of the show's cast were Close protégés. He spent the mid-to-late 1980s and 1990s teaching improv, collaborating with Charna Halpern at Yes And Productions and the ImprovOlympic Theater with Compass Players producer, David Shepherd. In 1987, Close mounted his first scripted show, Honor Finnegan vs. the
