Andrew Gemant

Background

Andrew Gemant was born in Nagyvarad, Hungary on July 27, 1895.

Education

During 1920-1922 he attended the University of Berlin and worked in the laboratories of Leonor Michaelis and Herbert Freundlich. He received his Doctor of Philosophy in physics in 1922.

Career

His work included a series of fundamental papers on viscoelasticity and fractional differentials, published in the mid 20th Century. He served in the Austro-Hungarian army as a medical student during the World War I and received his Doctor of Medicine from the University of Budapest in 1919. From 1923-1924, Gemant was a research physicist at Radiologie Incorporated, an X-ray tube manufacturer in Berlin.

From 1925-1931 he was a research physicist at Siemens-Schuckert Cable Company.

He held a privat-docent position at the Technical University of Berlin (Technische Universität Berlin) from 1929-1933, and from 1932-1933 he was a researcher at the Heinrich Hertz Institute (HHI) for Research on Oscillations. The Gemants then moved to the United States, where from 1938-1939 he was a research associate in the Electrical Engineering Department at the University of Wisconsin.

From 1940-1960 Gemant was a staff physicist at the Detroit Edison Company. He died in February 1983 at the age of 87.

Andrew Gemant performed research in the areas of: X-ray fluorescence.

PH of aqueous solutions. High voltage physics. Dielectrics; colloids.

Acoustics.

Viscosity and internal friction of solids. Electrets; electrochemistry of oils. Radioactive tracers in solutions.

High voltage cables.

Oxidative and photochemical ions in hydrocarbons. Ion-exchange resins in hydrocarbons. Solubilization of cholesterol.

Carcinogenesis.

Enzymic oxidative degradation of protein in senescence. And the reduction by chemical means of the reactivity of deoxyribonucleic acid (deoxyribonucleic acid) toward hydrogen peroxide in order to mitigate symptoms of aging. Andrew Gemant introduced the concept of complex viscosity which is often used for characterizing the viscous and elastic contributions to the rheological response measured in oscillatory shear experiments.

Politics

In 1933 Gemant was dismissed from his research and teaching positions by the National Socialist (Nazi) government.
