Anthony W. Norman


Anthony W. Norman was a distinguished 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.
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 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.
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.

Selected honors and awards

Through May, 2011, Norman had been credited with over 800 scientific publications dating back to 1959.

Personal

His wife, Helen Henry, predeceased him in 2018. He has three children and nine grandchildren.
