Robert Alexander Craig

Born in 1872, he was an American veterinarian and teacher whose work centered on livestock health. Purdue University’s archives describe him as a Professor of Veterinary Science in the university’s early years, and note that he earned his D.V.M. from Iowa State College of Agriculture in 1897. They also identify him as Veterinarian of the Indiana Experiment Station and as an active member of major veterinary organizations.

He is best remembered today for practical books on animal disease, especially Common Diseases of Farm Animals. Public-domain editions and library records connect his name with other veterinary titles on swine, sheep, and pork production, showing how strongly his writing focused on everyday agricultural needs.

What stands out about his work is its straightforward usefulness. Rather than writing only for specialists, he produced manuals that helped readers recognize illness, understand basic causes, and think in terms of prevention as well as cure. A confirmed portrait was not readily available from the sources found.
