Tom Dreesen, a stand-up comedian known for opening for Frank Sinatra and for pioneering work in American comedy, has died at age 86, according to multiple outlets. Several reports say Dreesen spent about 13 years touring the United States as Sinatra’s opening act, drawing on a long-running professional relationship with the singer. Dreesen also gained recognition earlier in his career for helping shape comedy that reached mixed audiences: he and Tim Reid formed “Tim and Tom,” one of the country’s first interracial comedy duos. The partnership began after the pair met in Chicago in 1969 and continued until the mid-1970s. While outlets describe Dreesen’s background differently, they consistently identify him as rising from difficult circumstances and later building a widely visible career through stand-up and screen appearances, including work credited in entertainment coverage such as “Spaceballs” and a “Columbo” TV movie. Reports also note that his family announced his death via a spokesperson or through an official Facebook post. None of the articles cited a specific cause of death.
