Biography of John Jay Jakosky 
Early years and Education
John Jay Jakosky was born at Vinita, Indian Territory (later Oklahoma) January 20, 1896. He received a B.S. in Mechanical Engineering at the University of Kansas in 1920, a B.S. in Electrical Engineering at the University of Pittsburgh in 1925, the Professional degree of Mechanical Engineer at the University of Kansas in 1926, and, after graduate work at the Carnegie Institute of Technology and the University of Arizona, a Doctor of Science degree from the latter in 1933.
From 1920-25 he acted as Research Engineer for the U. S. Bureau of Mines, chiefly in studies of underground communication, sub-surface attenuation, and similar matters. From 1925-28 he occupied the position of Physicist for the Western Precipitation Company and the Research Corporation, engaged principally in devising equipment for eliminating radio interference caused by high voltage precipitators. For a period of two years he served as a Consulting Engineer for the Southwestern Engineering Corporation, investigating high frequency inductive methods for shallow mineral exploration. In 1929 he organized International Geophysics, Inc.
In 1940 he resigned as President of International Geophysics to accept the position of Dean of the Schools of Engineering and Architecture and Director of the Engineering Experiment Station at the University of Kansas. In 1943 he accepted his present position as Director of Industrial Research and Assistant to the President of the University of Southern California. On leave, his present activities are devoted almost wholly to research concerned with the war.
From 1950 until his death in 1964, Jakosky was President and Director of Research for the Electrophysics Corporation, a manufacturer of electronic equipment.
Exploration Geophysics Textbook 
Jakosky was a member of the American Institute of Mining and Metallurgical Engineers (serving as a member of the Committee on Geophysics, the Committee on Geophysics Education, and the Committee on Mining Education), the American Association of Petroleum Geologists, the American Geophysical Union, the Society for the Promotion of Engineering Education, and the Society of Exploration Geophysicists (Vice-President, 1945-46). Academic organizations include Sigma Xi, Tau Beta Pi, Sigma Gamma Epsilon, Pi Tau Sigma, Theta Tau, and Delta Upsilon.
