Cynthia Plaster Caster(1947-2022)

In college, when her art teacher gave the class an assignment to "plaster cast something solid that could retain its shape", she hit upon the idea of casting erect male genitalia, which would then go flaccid and exit the mold. Finding a dental mold-making substance called alginate to be sufficient, she found her first celebrity client in Jimi Hendrix, the first of many to submit to the idea.
