Joel Henry Hildebrand

from Wikipedia, the free encyclopedia

Joel Henry Hildebrand (born November 16, 1881 in Camden (New Jersey) , † April 30, 1983 in Kensington (California) ) was an American chemist.

Hildebrand was already interested in chemistry at college and studied chemistry and physics at the University of Pennsylvania from 1899 with a bachelor's degree in 1903 and a doctorate in chemistry in 1906 with Edgar Fahs Smith with the thesis The determination of anions in the electrolyte way . He studied at the Humboldt University in Berlin with Jacobus Henricus van 't Hoff and Walter Nernst, among others, and then taught at the University of Pennsylvania. In 1913 he was invited by Gilbert Newton Lewis to the University of California, Berkeley , where he became an instructor, 1918 associate professor and 1919 professor. From 1949 to 1951 he was dean of the Faculty of Chemistry. In 1952 he officially retired, but continued to teach at the university until shortly before his death. A hall in Berkeley is named after him.

He was considered a leading expert in the physical chemistry of solutions, especially non-electrolytic solutions. Hildebrand introduced the term regular solutions. He was also considered a major chemistry teacher at Berkeley.

In the mid-1920s, he discovered the advantage of helium-oxygen mixtures when diving to avoid diving disease.

In 1953 he received the Willard Gibbs Medal , in 1962 the Priestley Medal and in 1939 the Nichols Medal. The Joel Henry Hildebrand Award of the American Chemical Society is awarded in his honor for achievements in chemistry of liquids. Hildebrand himself received the first prize in 1981. He had been a member of the National Academy of Sciences since 1929 and of the American Philosophical Society since 1951 . For 1955 he was elected President of the American Chemical Society. In 1946 he became an Honorary Fellow of the Royal Society of Edinburgh .

He was President of the Sierra Club from 1937 to 1940 . He wrote the book Camp Catering with his daughter Louise .
