Samuel Sugden

from Wikipedia, the free encyclopedia

Samuel Sugden (born February 21, 1892 in Leeds , † October 20, 1950 ) was a British chemist.

Sugden studied chemistry at the Royal College of Science in London from 1912 , worked as a chemist in a cement works after the outbreak of World War I and from 1916 at the Royal Arsenal in Woolwich. In 1917 he received his bachelor's degree from the University of London and in 1919 was a lecturer at Birkbeck College, University of London. In 1921 he received his master’s degree and in 1924 he received his doctorate (D.Sc.). In 1928 he became a reader and in 1932 professor of physical chemistry at Birkbeck College and in 1937 professor of chemistry at University College London. During the Second World War he was again involved in war-related research at the Ministry of Supply and, from 1944, with the US Air Force.

Sugden dealt with surface tension and in 1924 introduced the unit of measurement Parachor (molar volume of a liquid with the same surface tension). He also used surface tension to clarify bond relationships, for example when confirming Martin Lowry's hypothesis about the semipolar double bonds in sulfur and phosphorus compounds. In the 1930s he dealt with the relationship between electronic structure and magnetic properties of organic compounds and he measured dipole moments in gases. From 1939 he dealt with radioactive tracers .

He was a Fellow of the Royal Society .
