The sine qua non of pre-Stonewall drag artists, and certainly the most prolific, with an unprecedented 35 year legacy of 78's, 45's and LP's. His crazy life, mad career and tragic end (he died a convicted murderer in a Texas prison in 1971) deserve a decent biography.
Enormously popular (and just plain enormous) drag star of the 80's, whose work in John Waters' films is legendary.
T. C. Jones
Bald female impersonator whose dead-on impressions of Bette Davis, Tallulah Bankhead and Louella Parsons (among others) led to a successful stage and screen ("Promises! Promises!"; "Head") in the 50's and 60's
Famous 60's-70's San Francisco-based "gay actress" (his term, not mine) and drag comedian; undoubtedly the current grand dame of the genre.
RuPaul is far and away the most popular drag artist performing today and arguably the greatest "crossover" star of all time. RuPaul hit and stayed on the scene since the early 90's thanks to talent, good timing and-probably above all-a cheery, optimistic and fun spirit which contrasts sharply to the arch bitchiness of so many drag performers.
