Anthony W. Norman
Anthony W. Norman (January 1938 – June 14, 2019) was a professor emeritus of biochemistry and biomedical sciences at the University of California, Riverside and one of the world's foremost experts on vitamin D. Vitamin D Research. Norman's research was in the area of cellular and molecular endocrinology, where he was internationally known for his breakthroughs in the study of vitamin D. This included the mechanisms of action of the steroid hormone 1,25-dihydroxycholecalciferol, vitamin D structure-function relationships, and actions of the vitamin D receptor (VDR). In 1967, Norman's lab discovered that vitamin D  is converted into a steroid hormone by the body. In 1969 he determined that vitamin D receptors (VDR) were present in the intestine. In 1971 the Norman laboratory reported the chemical structure of the active form of vitamin D to be 1,25-dihydroxycholecalciferol (which is also known as 1α,25-dihydroxyvitamin D3, and 1α,25-(OH)D). In 1972, Norman in collaboration with Dr. Jack Coburn at the UCLA medical school treated the first uremic patients with the steroid hormone, produced in the Norman laboratory. Norman and others, including Dr. Cedric Garland of UC San Diego, in 2007/8 made the recommendation that the daily  intake of vitamin D for adults be revised to 2000 international units. Vitamin D workshops. One of his most recognised achievements was the organisation of 15 international Vitamin D Workshops which usually ran every three years from 1973 to 2012. Personal life. His wife, Helen Henry, predeceased him in 2018. He had three children and nine grandchildren. Publications. Norman has been an author on over 800 scientific publications dating back to 1959. A special issue on vitamin D dedicated to Norman's memory was published in 2021 with contributions from many of his collaborators and other notable scientists. Anthony W.
