J. Calvin Giddings

from Wikipedia, the free encyclopedia

John Calvin Giddings , called Calvin Giddings, (born September 26, 1930 in American Fork , Utah , † October 24, 1996 in Salt Lake City ) was an American chemist ( physical chemistry , analytical chemistry ). He is one of the pioneers of high performance liquid chromatography (HPLC) in the mid-1960s. Giddings was a professor at the University of Utah .

Giddings studied at Brigham Young University with a bachelor's degree in 1952 and the University of Utah, where he received his doctorate in 1954 under Henry Eyring . He was a post-doctoral student at the University of Wisconsin . From 1957 he was Assistant Professor, 1959 Associate Professor, 1962 Research Professor and 1966 Professor at the University of Utah.

Giddings contributed significantly to the theory of chromatography (non-equilibrium, diffusion, eddy diffusion, pressure change, flow in thin layers and paper, electrophoresis, etc.). His book Dynamics of Chromatography is considered a classic. With his contributions he optimized the HPLC . Giddings also developed the basic principle of field-river fractionation in the 1960s .

At first he also dealt with the theory of flames, quantum mechanics and chemical kinetics and later with considerations of probability in the context of a nuclear war, the physics of snow avalanches, and prediction of diffusion coefficients. He wrote an introduction to chemistry in the early 1970s with an emphasis on environmental aspects that particularly interested him.

In 1987 he received an honorary doctorate in Uppsala. He received the ACS Award in Electrophoresis and Chromatography and the Utah Section Award of the ACS. In 1978 he received the Tswett Medal and in 1991 the William H. Nichols Medal .

He was an outdoor activist and organized an expedition in 1975 that first explored the course of the Apumaric River in Peru, a source of the Amazon. Previously, he was on a 1974 Fulbright Fellowship for chemical research in Peru.
