Cannings, Fred E., d. 1979.

Cannings (d. 1979) was chief of technical facilities for Western Union Telegraph Company and responsible for installing and maintaining the telegraph circuit that connected the Japanese government and the Japanese embassy in Washington, D.C. in 1941. Based upon his work for Western Union, he believed that the Japanese government warned the U.S. before the attack on Pearl Harbor. He conducted research on the topic and often worked with Kilsoo Haan, a Korean national who was an agent for the Federal Bureau of Investigation.
