Theorell, Axel Hugo Teodor, 1903–82, Swedish biochemist, M.D. Caroline Institute, Stockholm, 1930. The results of an illness caused him to abandon his career as a physician, and he began to teach at the Univ. of Uppsala. He became (1937) professor of biochemistry and later head of the department at the Nobel medical institute, Stockholm. He was awarded the 1955 Nobel Prize in Physiology or Medicine for his discoveries concerning oxidation enzymes. Theorell was also the first to produce a pure form of myoglobin, the red-colored protein of muscles.
