Why did Dr. Frank J. O'Donnell write his name and the date "Dec. 20, 1924" on the 1910 supplement? As a field agent for the Montana State Board of Entomology, O'Donnell did control work for the prevention of RMSF and other tick-borne diseases endemic to the valley. Two notable things had happened in his life that year: He went from being a Montana state employee to a U.S. Public Health Service staff member, and he helped begin production of RMSF vaccine, enabling the promise of the Bitter Root Valley supplement to come true.(

Note

Note that “Bitterroot” is today’s preferred spelling.

Early residents of the Bitterroot Valley called the disease “black measles”, “blue disease”, “black typhus”, or just “fever.” RMSF appeared in the valley after the slope had been cleared of trees for timber to make railway ties for the Northern Pacific Railroad, leaving the perfect environment for ticks. In 1902, the state of Montana asked scientists to investigate the mysterious disease. In less than 22 years, researchers identified what caused the disease, how it was transmitted to humans, and created a life-saving vaccine. This was nearly a miracle in an age with little knowledge of virology and only basic technology.

This drawing shows the spotted fever rash on a leg. It was drawn in 1903 by Dr. John F.
