Tromp, S(olco) W(alie) (1909-1983)

Geophysicist, director of the Bioclimatological Research Center, Leiden, Netherlands, and writer on parapsychological subjects. Tromp was born on March 9, 1909, at Djarkarta, Indonesia. He moved to Europe for his education and earned his Ph.D. at the University of Leiden in geology in 1932.

After military service (1932-33), Tromp was a field geologist for oil companies in Indonesia and Egypt from 1933 to 1940. During World War II, he worked as an advisor on oil explorations for the Turkish Government (1940-43) and then joined his country's war effort as the director of economic warfare, Netherlands Army (1943-45).
