John G. Trump


John George Trump was an American electrical engineer, inventor, and physicist. A professor at the Massachusetts Institute of Technology from 1936 to 1973, he was a recipient of the National Medal of Science and a member of the National Academy of Engineering. John Trump was noted for developing rotational radiation therapy. Together with Robert J. Van de Graaff, he developed one of the first million-volt X-ray generators. He was the paternal uncle of President Donald Trump.

Early life

Trump was the youngest of three children and the second son of German immigrants Frederick Trump and Elizabeth Christ Trump. He was born in New York City on August 21, 1907.
John's brother, Fred, joined their mother in real estate development and management while still in his teens. Initially, John and his brother tried working together building houses, but ultimately they dissolved their partnership, and John pursued a career in electrical engineering.
Trump received his bachelor's degree in electrical engineering from the New York University Tandon School of Engineering in 1929, his master's degree in physics from Columbia University, and his doctorate of electrical engineering from the Massachusetts Institute of Technology in 1933. He was a professor at MIT from 1936 until 1973.

War service

During World War II, Trump switched from work on hospital X-ray machines to research into similar technologies, especially the development of radar. During 1940, he joined the newly formed National Defense Research Committee, as technical aide to Karl Compton, President of MIT and the Chairman of the Radar Division.
During 1942, Trump became Secretary of the Microwave Committee, a sub-committee of the NDRC. The director of the Microwave Committee was Alfred Lee Loomis, the millionaire physicist, who decided to create a laboratory. He selected a site for it, chose a suitably discreet and ambiguous name for it and funded the construction, until the Federal administration was established. The new institution was the MIT Radiation Laboratory, or the "Rad Lab". The British were also researching radar, which they termed Radio Direction Finder, and had started much earlier. Their Tizard Mission to the US showed how much more sophisticated they were with some of the technologies, particularly the magnetron. The US decided to send a team to Britain to help coordinate the efforts of the two Allies. The unit was known as the "British Branch of the Radiation Laboratory" and operated as a department of Britain's Telecommunications Research Establishment at Malvern, in Worcestershire.
In early 1943, two days after the death of Nikola Tesla, the Federal Bureau of Investigation ordered the Alien Property Custodian to seize Tesla's belongings. Trump was called in to analyze the Tesla items, which were being held in custody. After a three-day investigation, Trump's report concluded that there was nothing which would constitute a hazard in unfriendly hands.
From February 1944 to the end of the war in Europe, Trump was the Director of the BBRL. During this time, Trump also served in the Advisory Specialist Group on Radar, advising USAAF General Carl Spaatz on navigational radar, precision-bombing radar, and also defenses against the German radars found in their night-fighters and in their flak units. The systems included: Gee, Oboe, LORAN, H2X, MEW & SCR-584. Trump worked with all the most important British radar experts, including Sir Robert Watson-Watt, A.P. Rowe and Bernard Lovell. At the end of the war, Trump also had interviews with Germany's main radar technicians. Trump received recognition for his war-work partnership from both the United States and the United Kingdom.

Family

John G. Trump is a member of the Trump family. He married Elora Sauerbrun, and they had three children: the late John Gordon Trump of Watertown, Massachusetts; Christine Philp of New London, New Hampshire; and Karen Ingraham of Los Alamos, New Mexico; and six grandchildren. Trump's nephew, Donald Trump, has been President of the United States since 2017.

Later life

During 1946 Trump, Robert J. Van de Graaff, and Denis M. Robinson initiated the High Voltage Engineering Corporation to produce Van de Graaff generators.
He returned to MIT to teach and direct research for three decades after the war. He directed the MIT High Voltage Research Laboratory from 1946 to 1980. Some of his research at MIT concentrated on treating wastewater. He researched using an electron beam from a high voltage accelerator as the deactivating agent in the treatment of municipal wastewater sludge. The High Voltage Research Laboratory developed a prototype system that was tested at one of Boston's wastewater treatment plants and it was able to provide bacterial and viral disinfection via continuous on-line treatment. Trump died in Boston on February 21, 1985.
The National Academy of Engineering described Trump as "a pioneer in the scientific, engineering and medical applications of high voltage machinery". James Melcher, Trump's lab director, is quoted as saying: "John, over a period of three decades, would be approached by people of all sorts because he could make megavolt beams of ions and electrons – death rays... What did he do with it? Cancer research, sterilizing sludge out in Deer Island , all sorts of wondrous things. He didn't touch the weapons stuff."
