Professor of Biochemistry at the UW
In 1923, Steenbock demonstrated that irradiation by ultraviolet light increased the vitamin D content of foods and other organic materials.
After irradiating rodent food he discovered that the rodents were cured of rickets. It is now known that Vitamin D deficiency is a cause of rickets.
Steenbock's irradiation technique was used most memorably for milk and by 1945 rickets had all but been eliminated.
