"The Alexanderson radio alternator was a high-power, radio-frequency source which provided reliable transoceanic radiotelegraph communication during and after World War I. Ernst F.W. Alexanderson (1878-1975), a General Electric engineer, designed radio alternators with a frequency range to 100 kHz and a power capability from 2 kW to 200 kW.

From 1956 to 1993, the GE Re-entry Systems facility was home to thousands of engineers and technicians who solved the problem of vehicles successfully reentering the Earth’s atmosphere. As described by aerospace pioneer Theodore Von Karman, “ Reentry… is perhaps the most difficult problem one can imagine.” Whether it was the first operational reentry vehicle for the Atlas ICBM, the recovery of the first man-made object from orbit, or the first probe to enter Jupiter’s atmosphere, some of the most significant milestones in aerospace were accomplished by those working in this facility.
