Boris Pregel

Boris Pregel (; 24 January 1893 – 7 December 1976) was a Russian Empire–born Jewish engineer and dealer in uranium and radium. He was born in Odessa, in the Russian Empire, and studied engineering in Belgium at the Free University of Brussels and the University of Liège. He served in the Russian army in World War I, entering as a private soldier and rising to the rank of colonel of engineers. He was put in charge of Russia's only aircraft factory. He moved to Paris after the October Revolution.

In Paris he came in contact with Edgar Sengier, a Belgian mining engineer, who was effectively in charge of the mining company, Union Minière, in the Belgian Congo. Pregel became interested in the radium department of this company. From the 1920s to the Second World War Pregel and Sengier controlled the world's supply of radium. He also promoted the building of many radio-therapy installations, including the Queen Sofia Hospital (Sophiahemmet) in Sweden.

After his arrival in the US he established, with his brother Alexander, the Canadian Radium and Uranium Corp of New York George B. Pegram and his associates at Columbia University, who did some of the initial work on the Manhattan Project, sought Pregel's assistance because they did not have sufficient money to buy the uranium.

In March 1945 the Canadian Foreign Exchange Control Board began formal hearings into Pregel's financial dealings. The case was settled out of court but Pregel and the other defendants paid over $1 million in cash and other assets to settle. Furthermore, Pregel agreed to terminate his agency agreement between Eldorado and the Canadian Radium & Uranium Corp.

In 1946, in a speech to The New School, Pregel shared his thoughts on the nuclear world he had helped bring into being:

He served as president and board chairman of the New York Academy of Sciences, as president of the French University (Ecole Libre) in New York, as trustee of the New School for Social Research and as vice-president of the American Geographical Society. He received several honorary degrees and foreign decorations. Pregel founded the Boris Pregel Awards for science, awarded by the New York Academy of Sciences.
