Stephen Moulton Babcock, 1843-1931, was a professor of agricultural chemistry at the University of Wisconsin. He is best known for the Babcock test, a method of measuring butterfat content in milk. His research on the nutrition of dairy cattle paved the way for the discovery of vitamin A.
Danish physical chemist (1879-1947) known for a widely applicable acid-base concept identical to that of Thomas Martin Lowry of England. He was also an authority on the catalytic properties and strengths of acids and bases.
English chemist who discovered of the effects of nitrous oxide, which came to be known as laughing gas. He also undertook the first electrochemical decompositions, isolating potassium, barium, strontium, calcium, and magnesium.

Martin David Kamen (1913-2002) co-discovered carbon-14 in 1940 with Samuel Ruben. In 1944 he was expelled from the Lawrence Radiation Laboratory as a security risk. During his later career he focused on the biochemical processes of photosynthesis. In 1961 he joined the University of California, San Diego Chemistry Department, where he acted as a "founding father" of the new campus.
Largely because of his introduction of conservation of mass and his rejection of phlogiston, Antoine Lavoisier is considered to be the father of modern chemistry.
