Aaron Bodansky (1887 in Elizabethgrad – 1960) was a Russian-born American biochemist remembered for describing the Bodansky unit in the measurement of alkaline phosphatase in blood. Bodansky was born in Russia in 1887 and emigrated to the United States in 1904, followed in the next two years by his parents and siblings. He studied biochemistry at Cornell University, earning a Ph.D. in 1921 with a thesis titled "Enzyme studies on solanum elaeagnifolium". In 1926, Bodansky was hired into the laboratory division of the Hospital for Joint Diseases (now part of NYU Langone Medical Center). At the Hospital for Joint Diseases, Bodansky's work covered a variety of areas of biochemistry including thyroxin and insulin metabolism, metabolism of minerals and bones, liver function, and parathyroid func
