His Professional Career

While Trump was the faculty member at the Massachusetts Institute of Technology, he studied the voltage-insulation properties of high vacuum and compressed gases. Later on, he designed one of the first million-volt X-ray generators while working with Prof. Robert J. Van de Graaff. The generator was first used clinically at the Collis P. Huntington Memorial Hospital in Boston around 1937.

In 1946, he alongside Dr. Van de Graaff and Dr. Denis M. Robinson created the Van de Graaf Electrostatic generator from their company, High Voltage Engineering Corporation.

In 1946, he founded the High Voltage Engineering Corporation along with  Dr. Van de Graaff and Dr. Denis M. Robinson. A few years before, Dr. Trump was busy in developing radars. In 1944, he was appointed the director of the British branch of MIT Radiation Lab in 1944.

After the war John G. Trump became the Department of Radiology at the Lahey Clinic in Boston and later on, was appointed as the Chairman of its board and under his direction, rotational radiation therapy was developed. He also developed the use of high energy electors for the treatment of superficial skin lesions.

In 1973, he became the professor emeritus at M.I.T. as a senior lecturer. Apart from all this, he was also the author of around 80 scientific publications.
