Pisector

Someone who tries to subdivide an angle into π parts using only a pair of compasses and an unmarked ruler.

Just as the trisectors of yesteryear tried to prove the impossible, pisectors are hell-bent to achieving their goal, hoping that their proofs would bring them mathematical fame or immortality—when being dubbed a “mathematical crank” feels less bitter than being a nobody or fading in obscurity.
