Typhus triumvirate of the United States Public Health Service: (left) Eugene Rollo Dyer; (center) Adolph Rumreich; (right) Lucius Badger. Along with William Workman and Elmer Ceder, these men determined that FBT has a domestic rodent reservoir and is transmitted by the flea feces and discovered the vector potential of the Oriental rat flea. In 1931, the team also differentiated FBT from Rocky Mountain spotted fever (RMSF). For his work on typhus, Dyer was awarded the Sedgwick Memorial Medal for Distinguished Service in Public Health in 1950 [83].
