In 1903, Dr. John F. Anderson of the U.S. Public Health Service’s Hygienic Laboratory (forerunner of the National Institutes of Health) was sent to Montana to study RMSF. Unusual for the time, he was a trained bacteriologist. He worked with Chowning and Wilson and made several drawings of patients with RMSF, and also of what he saw in his microscope. His colleague, Dr. Charles Stiles, would later name the tick identified as carrying RMSF after Anderson: Dermacentor andersoni. Anderson would go on to be the director of the Hygienic Laboratory and vice president of E. R. Squibb & Sons pharmaceutical company.
