When it comes to science and technology, the United States is undoubtedly one of the hubs of scientific research and discoveries. Biochemistry, the study of the structure, composition, and chemical reactions of substances in living systems, emerged as a specific scientific discipline around the early 19th century. John Jacob Abel, an influential American biochemist and pharmacologist, is credited to have founded and chaired the first department of pharmacology in the United States at the University of Michigan in the late 19th century. Max Henius who co-founded the American Academy of Brewing in Chicago, was an expert in the fermentation processes. In a male-dominated field, biochemist Gerty Theresa Cori became the first American woman to win a Nobel Prize in science and the first woman to be awarded the Nobel Prize in Physiology or Medicine. Another prominent biochemist was Lafayette Benedict Mendel who studied nutrition and conducted vital research on Vitamin A, Vitamin B, lysine and tryptophan. Coming to contemporary times, T. Colin Campbell is well known for his studies on nutrition and was one of the lead scientists of the China–Oxford–Cornell study on diet and disease.
