The reflection seismograph: Its invention and use in the discovery of oil and gas fields, ca. 1973.

Karcher's autobiography largely tells of his invention of the reflection seismograph and his development and use of it for finding oil, gas, and mineral deposits. Born in Indiana, Karcher studied physics and electrical engineering as an undergraduate at the University of Oklahoma. He began graduate work on x-rays in 1916 at the University of Pennsylvania. His studies were interrupted by World War I, during which he worked for the United States Bureau of Standards on detecting and locating enemy artillery by measuring sound waves. When he returned to school he began applying his war work to the search for oil and gas. He spent most of his career developing and applying that technology, which he did through his company, Geophysical Service, Inc. from 1930 into the 1970s. Karcher mentions a short period in 1917 in which he worked in the Thomas Edison Laboratory as important for the lessons of perseverance and persistence he learned from Edison.

Thomas Alva Edison (born February 11, 1847, Milan, Ohio – died October 18, 1931, West Orange, New Jersey), American inventor and businessman who has been described as America's greatest inventor. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrial...

In 1919 Edward Bushnell was appointed publicity agent for the University of Pennsylvania. His appointment began a long and expanding effort at public relations at the University. In 1954 the Department of Public Relations expanded its work to include two new units, Motion Picture Services and the Office of Radio and Television. These two offices operated until 1975 when they were phased out of a stream-lined department. From the description of University Film Collection, 1915-1989. (...
