educating thousands of nondestructive test personnel in the theory, techniques, equipment and interpretation of eddy current tests. 15 This integrated presentation was then used throughout the world to update eddy current test technology. The unique developments in Förster’s new laboratory in Reutlingen, Federal Republic of Germany, were made known in the United States not only by those who read his German publications before 1950 but also through missions in which American personnel were sent to Förster’s laboratory for education and experience with these new forms of test instrumentation. Richard Hochschild, for example, made a visit of perhaps six months to Reutlingen. Upon his return, he prepared summary reports that were distributed by the Atomic Energy Commission, the sponsors of his visit. 16 In the United States, numerous facilities began research to test these new concepts and instrumentation, including significant efforts at Oak Ridge, Hanford and other facilities. The creative work of Hugo L. Libby at Hanford and others at Oak Ridge may well have been sponsored in response to the original work done by Förster. Even more significant was the transfer of Förster’s technology to American firms manufacturing and distributing nondestructive test equipment since 1952. Förster made his first presentation before an ASNT audience in the early 1950s after learning a very little English aboard ship. Agreements for licensing under Förster patents were later concluded. The nondestructive testing staff at Battelle Memorial Institute in Columbus, Ohio, modified the basic Förster instruments for use with United States components and electron tubes. During the next few years, increasing amounts of Förster’s technology were transferred to Magnaflux, whose staff under Glenn L. McClurg became qualified in design and production of Förster’s various instruments and then marketed these electromagnetic induction test systems throughout the United States. The collaboration between Förster and the Magnaflux Corporation lasted perhaps ten years, during which rapid progress was made both in the German laboratory and in the United States. Proliferation of Eddy Current Equipment Upon termination in the 1960s of the arrangement with Magnaflux, Förster marketed his instruments through the Foerster-Hoover organization in Ann Arbor, Michigan. Rudolf G. Hentschel, who was trained in Reutlingen at Institut Dr. Förster, transferred information to this new organization. After a few years, the licensing of Foerster instruments to Automation Industries resulted in further transfer of advanced technology and marketing through a new organization. A later arrangement with Krautkramer Branson repeated this unique educational process.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
