Bassen, Frank Albert (1903–2003),
American hematologist. Bassen practiced as an internist and hematologist at New York's Mount Sinai Hospital from 1933 to 1978.
Kornzweig, Abraham Leon (1900–1982),
American ophthalmologist. Kornzweig served as clinical professor of ophthalmology at New York's Mount Sinai School of Medicine. He pioneered the field of geriatric ophthalmology and founded the Society of Geriatric Ophthalmology. In 1950 Bassen and Kornzweig identified and described the causes and features of the rare autosomal recessive disorder that now bears their names. Their description was based on abnormalities found in an 18-year old girl. In a follow-up report published in 1957 they found the same set of abnormalities in the girl's brother.
