Fellow of the American Society of Animal Science Among those made Fellows of the American Society of Animal Science at the 64th annual meeting at Virginia Polytechnic Institute and State University, Blacksburg, July 29 to August 2, 1972, was Dr. Elmer Roberts. The citation read: "Elmer Roberts, geneticist, pioneer, prophet, philosopher and historian combined all these attributes and abilities in his unusually long and extended career in animal science." "He was born June 29, 1886, at Burnside, Kentucky, and spent his boyhood on the family farm. He received the B.S. degree in General Agriculture from the University of Illinois in 1913, and continued his graduate study receiving the Ph.D. degree in genetics in 1917." "Dr. Roberts was a faculty member of the University of Illinois until his formal retirement in 1954 and he has continued to devote his time and talent to special University assignments. While primarily serving the Department of Animal Science, he elicited the interest and enrollment of students from all areas of the University and continued his interdisciplinary teaching until recently." "He was a pioneer in his understanding of and concern for population control, particularly in
densely inhabited areas such as China. His international involvement in China predated our long lapse in relationships with the Mainland." "His research in genetics covered a wide spectrum of animal life—from laboratory species such as drosophila, mice, rats and rabbits, to chickens, sheep, swine, cattle and horses, and finally, man. He has long been interested in the relation of heredity to disease—specifically resistance and susceptibility to infection as influenced by hereditary factors. This problem was explored in detail in the study of pullorum disease in young chicks. After finding unmistakable evidence of hereditary resistance in strains of chickens kept at the University of Illinois, he spent a year (1929 to 1930) at Tunghsien, China, near Peking, where he worked with staff members of Peking Union Medical College, and found that small-type Chinese chickens had, through natural selection, developed resistance to Salmonella pullorum under conditions in which no disease control methods were in general use." "Other animal studies involved color inheritance in Shorthorn cattle, hairlessness in swine, crossbreeding in swine, twinning in Shropshire sheep, fertility in sheep and swine, anhidrosis in man, and
