ROSENHEIM, OTTO (1871–1955), British biochemist, born in Germany. In 1895 he went to teach at the University of Manchester and in 1901 moved to King's College, London, where he taught physiology. Later he was reader in biochemistry in the University of London until 1920. In 1925 he started 20 years' work at the National Institute for Medical Research in Hampstead. His published studies deal with the constituents of the brain, spermine phosphate, uric acid, toxicity, putrefaction, the placenta, and particularly sterols (including ergosterol) and vitamins D and A. Tests for detecting vitamin A in cod liver oil and for the determination of total sulfates in urine are named after him. -BIBLIOGRAPHY: King, in: Nature, 175 (1955), 1019–20; idem, in: Journal of the Chemical Society (1956), 799–801.
