Career
A native of Minnesota and an engineer by training, he authored several books on construction. He is best remembered for his political activities. Deatherage was an important player in domestic and international anti-Jewish circles in the 1930s and 1940s, including collaboration with the Welt-Dienst/World-Service propaganda agency headed by German Ulrich Fleischhauer.
Both were also defendants in the Great Sedition Trial of 1944.
In November 1952, Deatherage was living in Baltimore when he wrote to J. Edgar Hoover alleging ties between Presidents Roosevelt and Truman, referring to Tom Clark as a "Texas pussywillow". He further suggested that Huey Long was assassinated with "Washington" being aware "eleven minutes ahead of time".
