In the early 1920s, Harry Steenbock (1886-1967), a biochemist at the University of Wisconsin-Madison, developed a process to increase the vitamin D in food products such as milk by exposing them to ultra-violet radiation. Vitamin D was critical for preventing rickets, a common nutritional deficiency disease. In 1925 Steenbock helped establish the non-profit Wisconsin Alumni Research Foundation (WARF) in order to manage and license the irradiation process as well as other patents developed at the University. The irradiation process was patented in1928, US patent 1680818, and assigned to WARF. Borden's began irradiating milk in 1934.
