Type Fifteen Fan
from Fancyclopedia 2 ca. 1959
In a graphology article Joe Gilbert analyzed the chirographies of a number of well-known fans, and left it to the reader to guess which was which. Number 15 on the list was supposed to be a dangerous maniac that you shouldn't allow behind your back especially in a dark alley. Immediately each fan on the list of analyzees, and some others, leaped forward and identified #15 — as himself. Finally Gilbert said that he'd known very little about graphanalysis at the time, and his sketch of #15 was all wet; there was merely a little mental quirk in that fan. But fandom wouldn't have it so. Speer finally found out from Tucker that #15 was Fortier.

Courtesy Bob Tucker, Cy reveals for the first time that the actual Number 15 was Joe Fortier.
