John Verhoogen

John Verhoogen (born Jean Verhoogen, 1 February 1912, Brussels – 8 November 1993) was a Belgian-American geologist and geophysicist.

Verhoogen became ill at age 17 from poliomyelitis, which caused him problems throughout the rest of his life. Nevertheless, he studied mining at the University of Brussels (Ingénieur des Mines, degree 1933) and engineering geology at the University of Liège (Ingénieur-Géologue, degree 1934). He then went to the US, where he studied at the University of California, Berkeley under Howel Williams. In 1936 he received his doctorate in geology (with thesis Geology of Mt. St. Helens, Washington) from Stanford University, although most of the doctoral work was supervised by Williams at Berkeley. Verhoogen was then at the University of Brussels from 1936 to 1939. During the late 1930s and World War II, he was in the Belgian Congo, where he studied the volcano Nyamuragira and worked on the procurement of strategic mineral resources. From 1947 he was at the University of California, Berkeley, where he became a professor and remained until his retirement in 1976. and received the André Dumont Medal of the Belgian Geological Society. From 1951 to 1954 he was Vice President of the International Association of Volcanology and Chemistry of the Earth's Interior.
