Algeristic Home Made For (sum). Martin Alger of Detroit ("Photo- Fanatic Lensman") has a fabulous number of tools and much facility with them; once he made his own mimeograph and published on it a one-shot instructing the fan how to make his own mimeo for $3.75. (Of course other fans like Dale Tarr and Bill Danner had made their own flatbed mimeos, but Alger's was the first rotary job.) The renown of this feat spread till Martin became mythologically credited with infinite manufacturing potential and a mania for making things himself at the lowest possible prices, from Heironymus machines (which see) to thermonuclear devices ("AHMF $1.35 — not counting the hydrogen").
from Fancyclopedia 2 Supplement ca. 1960
Alger's wasn't the first rotary homemade mimeo; Dale Tarr had made one, too, in the longago. There's a rumor that Boff Perry did the same.
