Vernam, with no seniority, was soon out. He went to Postal Telegraph
Cable Company, which merged with Western Union. His inventive spark
flared from time to time, and he was granted 65 patents in all, among
them such important noncryptologic items as the semiautomatic torn-
tape relay system, the push-button switching systems, and finally the
fully automatic telegraph switching system, all for the Air Force's
200,000-mile domestic network.
But the reversal in his personal fortunes seemed to depress him. Each
night he sank deeper and deeper into the newspaper. Finally, on
February 7, 1960, after a long bout with Parkinson's disease, the man
who had automated cryptography died in obscurity in his home in
Hackensack, New Jersey.
