American mammalogist who published much on the mammals of the Neotropics, particularly primates and rodents, and described almost 70 new species and subspecies of mammals. About a dozen species have been named after him.
He attended the Universities of Pittsburgh and Michigan and lived in South America collecting mammals. In 1947, he was appointed a curator at the Field Museum of Natural History in Chicago and he continued to work there until his death.
He worked in Brazil on several occasions, the last in 1992, after which his health prevented him from going. He died from complications resulting from bone cancer at the Northwestern Memorial Hospital in Chicago on 15 February 1997 at the age of 87; he continued to work on his mammalogical research until two weeks before his death.
