John R. Mohler was the first living veterinarian to be inducted into the Saddle & Sirloin Portrait Collection. Born in Philadelphia, Mohler graduated from the veterinary department of University of Pennsylvania in 1896.


The following year, he accepted a livestock inspection position with the U. S. Bureau of Animal Industry during the tick fever quarantine and hoof and mouth outbreaks. Later, while serving the Bureau’s meat inspection division in Milwaukee, he studied for two additional years at the Medical College of Marquette University. He then transferred to the Pathological Division of the Bureau in Washington, D. C., where he achieved notable success investigating the cause and treatment of many animal diseases.
