Stephen Willis Stiles (July 16, 1943 – January 11, 2020)[1] was an American cartoonist and writer, coming out of the science fiction fanzine tradition.

[1] Stiles studied at The High School of Music & Art and the School of Visual Arts in Manhattan and later wrote about this in his essay, "Art School": ...in 1956, at age 13, I took the entrance exams at M&A, which partly consisted of drawing an arrangement of old shoes and flowers, as well as a review of my portfolio pieces — which included two issues of my first fanzine, Sam; that was a lucky break because my interviewers had never heard of a kid pubbing an ish and thought the whole concept incredibly creative.

And here I was studying in the same school that my heroes Harvey Kurtzman, Bill Elder and John Severin – the guys at Mad — went to, so it was pretty heady.

A fanzine interlineation he coined ("Death is nature's way of telling you when to stop") became a national catchphrase after it was reprinted in Pageant in 1962.

[3] His work (art and text) has since appeared in leading fanzines (Xero, Void, Mimosa, Trap Door) as well as the more obscure (Vojo de Vivo).

In 1968, Stiles was the Trans-Atlantic Fan Fund winner, attending Thirdmancon, the 1968 Eastercon in Buxton, Derbyshire.
