Alfred Nier

from Wikipedia, the free encyclopedia

Alfred Otto Carl Nier (born May 28, 1911 in Saint Paul , Minnesota , † May 16, 1994 in Minneapolis ) was an American physicist . He pioneered the field of mass spectrometry .

Life

Nier was the son of German immigrants. After studying as an engineer of electrical engineering in 1931, he began to become arbeitlos during the Great Depression , a degree in physics . His work at Harvard University , supported by a scholarship, led to the publication of the relative abundances of the isotopes of the element uranium in 1938 . In the same year he became a Fellow of the American Physical Society . Apart from his stay at Harvard from 1936–1938 and his work from 1943 to 1945 on the Manhattan Project in New York City at the Kellex Corporation, he worked at the University of Minnesota in Minneapolis throughout his academic career . In 1980 he also received an honorary doctorate there.

Since 1950 he was a member of the National Academy of Sciences . In 1980 he was elected a member of the American Academy of Arts and Sciences . He was a member of the American Philosophical Society and a foreign member of the Royal Swedish Academy of Sciences . In 1985 he was the first recipient of the Frank H. Field and Joe L. Franklin Award for Outstanding Achievement in Mass Spectrometry from the American Chemical Society .
