In 1870, the first course in veterinary science, which gave "practical instruction in the care and treatment of sick animals," is taught by Dr. H.J. Ditmers, just 3 years after the university was chartered.
Starting in 1885, with the help of Dr. Donald McIntosh, who came to Illinois with a Doctor of Veterinary Science degree from the Toronto Veterinary College, the public was able to bring animals to free Saturday veterinary clinics for examination and treatment.
