<p><b>New page</b></p><div>In 1923, American biochemist [[Harry Steenbock]] at the [[University of Wisconsin]] demonstrated that irradiation by ultraviolet light increased the vitamin D content of foods and other organic materials. After irradiating rodent food, Steenbock discovered the rodents were cured of rickets. Using {{US$|300}} of his own money, Steenbock patented his invention. His irradiation technique was used for foodstuffs, most notably for milk. By the expiration of his patent in 1945, rickets had been all but eliminated in the US.</div>FuzzyBot
