in Bloomington. When he was 14 he began living and working on a farm
near Odin, where he got a high school education. He headed West at 19,
and, after selling a timber claim in California to a sawmill where he
worked for a time, he turned to carpentry and built and sold houses in
Fresno. Soon after he turned 40, he somehow became interested in
cryptology. Hebern was at this time a blue-eyed, brown-haired man of
medium height and build, mustachioed, quiet, a great reader, kind, and
even-tempered.
From 1912 to 1915, he filed for patents for cryptographic check-
writing devices, cipher keyboards for typewriters, movable letter blocks to
form mixed reciprocal monoalphabets, and a ciphering typewriter. In
1915, he devised an arrangement in which two electric typewriters were
connected by 26 wires in random fashion; thus when a letter was struck
on the plaintext keyboard, it would cause a ciphertext letter to print on
the other machine
