Mark Morris (to those unfamiliar with veterinary history) was the founder of Morris Animal Foundation, the world's largest non-profit organization, funding humane animal health research and studies.
To most folks, he's best remembered as the guy who developed Science Diet and Hill's, the largest pet food company in the world (and since sold to Colgate).
Sometime in his busy schedule he also started up a veterinary education record label. No telling how many of these were produced, and how many topics there are, but the two records Bucks found are dated 1961 ("Diagnosis and Management of Liver Disease"), and 1963 ("The Aged Dog").
