James E. Tilma started in the GE test program in 1942 after graduation from the University of Nebraska. He began testing motors at GE, and during World War II also tested diesel submarine propulsion systems. Through his career at GE he worked with a variety of motor projects including hydroelectric generators, paper mill equipment, and motors for nuclear power stations. He finished his career for GE in 1980 as manager of the Large Induction Motor Product Engineering Department.
Materials used by J.E. TIlma during his career as an engineer at General Electric from 1942-1980, including three data folders (binders) from the Alternating Current Engineering Department and his test manual. Also includes Tilma's individual experience record at GE, an article he wrote, "Major Motors for Nuclear Power Stations" for Power Engineering magazine, and an oversized photograph of a wind tunnel for which he helped design and install the propulsion motor
