| History: |
Something about McElroy from Tom French's publication: "Theodore R. McElroy -- Ted, or T.R., or Mac (he hated his given name) -- was born in September 1904. He began his telegraphic career at age 14, as a Western Union messenger, and within a year he was a telegraph operator. By age 21 he was winning code receiving contests and setting records. He set the all-time, still-unbroken official record of 75.2 words per minute in 1939 (corrected to today's 25-dot word standard, that would be 72.2 wpm). McElroy began manufacturing telegraph keys (his "Mac-Key") in late 1934. By 1941 he had put out about twenty variations of his semi-automatic key, and several variations of straight (hand) keys. There were also code practice oscillators, inked tape keyers and, for the military during WWII, many automatic Morse devices and code training equipment. Mac made millions of dollars during the war, but when demand shrivelled after the war, he lost most of it. In 1955 he sold his company (by then located in Littleton, Mass.). He continued to work for it for a while, then for other electronics companies. He gave code demonstrations, and became interested in local politics. McElroy died in November 1963. Hand keys, also called straight keys, were made by T.R. McElroy from 1937 to 1943. During the war, McElroy was busy making equipment for the Signal Corps, and key production was taken over by Telegraph Apparatus Company of Chicago (McElroy was a partner in T.A.C.)." For the season 1941/42 the Allied catalog for 1942 shows on page 136 quite a few of the popular transmitting keys.
