Elmer Otto Kraemer (27 February 1898 – 7 September 1943) was an American chemist whose studies and published results materially aided in the transformation of colloid chemistry from a qualitative to a quantitative science. For eleven years, from 1927 to 1938, he was the leader of research chemists studying fundamental and industrial colloid chemistry problems and a peer of Wallace Hume Carothers at the Experimental Station of the E. I. du Pont de Nemours Company where both men contributed to the invention of nylon that was publicly announced on 27 October 1938. The 1953 Nobel Laureate in chemistry, Hermann Staudinger, had a high regard for the American pioneers in polymer chemistry, particularly Kraemer and Carothers ==Early work== Elmer Kraemer was born in Liberty, Wisconsin on . In 1918, he received his B.S. degree from the University of Wisconsin. He remained there as instructor working with Prof. Louis Kahlenberg toward a Ph.D. degree. In 1921 he was awarded an American Scandinavian Fellowship and he spent a year in Sweden doing research on colloid chemistry with Prof. The Svedberg, the 1926 Nobel laureate in Chemistry. He continued his colloid chemistry research with Herbert Freundlich at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry in Berlin, Germany before returning to Wisconsin. For most of 1923 he worked on the kino-ultramicroscope and during part of the year assisted Prof. The Svedberg when Svedberg served as a guest lecturer at the University of Wisconsin. A year later, in 1924, Kraemer was granted his Ph.D. degree at the University of Wisconsin.
