Ludwig Frederick Audrieth

from Wikipedia, the free encyclopedia

Ludwig Frederick Audrieth (born February 23, 1901 in Vienna , † January 28, 1967 in Champaign , Illinois ) was an American chemist .

Life

He came to the USA with his parents in 1902 and studied at Colgate University in Hamilton (New York) with a bachelor's degree in 1922 and a doctorate in inorganic chemistry from Cornell University in 1926 . He then became an assistant there and worked with AW Browne. It was in New York that his interest in nitrogen compounds and reactions in non-aqueous solutions began. From 1928 until his retirement in 1967 he was at the University of Illinois at Urbana-Champaign , where he was Professor of Chemistry. In 1959 he took a leave of absence and was a science attaché at the US embassy in Bonn until 1963. He was also visiting professor at the Foreign Services Institute in Washington, DC

In 1931/32 he was a visiting scientist with Paul Walden at the University of Rostock , where he learned to work with liquid ammonia as a solvent. Chemistry with non-aqueous solvents was one of his main areas of research.

He dealt with sulfonamides and sulfamic acids and their derivatives. In 1939 he and Michael Sveda discovered the artificial sweetener sucaryl , the sodium salt of cyclohexylsulfamic acid . It came on the market in 1950.

In 1938 he recognized the potential of hydrazine as a high-performance fuel and in the 1950s he developed production methods for this and other rocket fuels. He held 15 patents on explosives and rocket propellants.

He was one of the founders of the Inorganic Synthesis series and co-editor from 1934 to 1967, and made many contributions to the series.
