Person

Robert Sarbacher
Smith's 1950 source on a secret Vannevar Bush group, and the origin of the claim that von Neumann and Oppenheimer were involved (his 1983 letter).
American physicist and Defense Department research consultant. In 1950 he told Canadian engineer Wilbert Smith that the recovery of flying saucers was the most highly classified subject in the US government, and Smith's memo of 21 Nov 1950 names Vannevar Bush as heading the small group studying it. In a letter to researcher William Steinman of 29 Nov 1983, Sarbacher added von Neumann and, he thought, Oppenheimer, while saying he could not attend the meetings himself.
