Del Close is perhaps the least famous of the great comedy maestros of the latter half of the 20th century. The performers he worked with, directed, or taught at the Compass Players in Saint Louis, the Committee in San Francisco, and Second City and the ImprovOlympic in Chicago constitute a who\'s who—Elaine May, Mike Nichols, Shelly Berman, Fred Willard, Joe Flaherty, John Belushi, John Candy, Bill Murray, Mike Myers, Vince Vaughn, Tina Fey, and Stephen Colbert, to name only a handful. But his ultimate legacy might be theoretical: Close led the movement to reinvent improvisation and establishit as an art form.\n\nAs he lay on his deathbed in a Chicago hospital in 1999, his friends flew in from around the country to throw him one last birthday party.\n\nVideo from ChicagoReader.com.
