I've been collecting names of famous people and celebrities for over 40 years, and the lists have been published in many sources. Maurice Ashley used my list in his chapter on celebrities in his book Chess for Success. Here is an alphabetical list (and reference) of 1192 famous people who play(ed) chess. If you have other celebrities or famous people not on this list who play chess (with a good reference), let me know and I will add it to the list.

Did anyone mention Duchamp? He was an artist that actually quit art to do chess. He played in several Olympiads, although he was never among the best in the world (his country, France, maybe).
