John Clarence Karcher (April 15, 1894 – July 13, 1978) was an American geophysicist and businessman. He invented and eventually commercialized the reflection seismograph, applying for patents in 1919. By the patenting, and development of reflection seismography, he created the means by which most of the world's oil reserves have been discovered. In 1930 he, Eugene McDermott, and Everette Lee DeGolyer founded Geophysical Service Incorporated, a pioneering provider of seismic exploration services to the petroleum industry that focused on reflection seismology.
