William A. Noyes - Career

Career

After receiving his doctorate, Noyes taught a year as an instructor at the University of Minnesota. He was next a professor of chemistry at the University of Tennessee, followed by seventeen years at Rose Polytechnic Institute in Terre Haute, Indiana (starting there in 1886). In 1903, Noyes was hired as the first "Chief Chemist" for the United States National Bureau of Standards in Baltimore, Maryland. His determination of atomic weights lead to "one of the most precise chemical determinations ever made", the ratio of the masses of hydrogen to oxygen (which he found to be 1.00787:16). With H.C.P. Weber, he received the Nichols Medal in 1908 for determining the atomic weight of chlorine.

In 1907 he became chair of the Chemistry Department at the University of Illinois at Urbana-Champaign, a position he would hold until 1926. In the process, he helped it to become one of the leading departments of chemistry in the United States. Despite his earlier work in analytical chemistry, Noyes is perhaps best known as an organic chemist. He was the first to prove the structure of camphor definitively and studied rearrangements in camphor and related compounds. He also worked on "electronic theories of valence, and the valence and nature of nitrogen in nitrogen trichloride" as well as developing "methods for the determination of phosphorus, sulfur, and manganese in iron".
