Active in the final decades of the 19th century, William Heyser Harbaugh was an American veterinarian associated with the United States Bureau of Animal Industry. Library of Congress records identify him as W. H. (William Heyser) Harbaugh, 1856–1897, and list him among the contributors to Special Report on Diseases of Cattle and on Cattle Feeding (1896).
He is also connected with Special Report on Diseases of the Horse, another substantial government work on livestock health. These publications were written for a broad practical audience and reflect the growing effort of the period to apply veterinary science to everyday agricultural problems.
Although not much biographical detail was easy to confirm, the surviving record shows a writer whose work belonged to an important moment in American agriculture, when better understanding of animal disease could make a real difference for farmers and food production.
