Bertrand Goldschmidt

Bertrand Goldschmidt was a French chemist, born in Paris on 2 November 1912 and died 11 June 2002 also in Paris. He is considered one of the fathers of the French atomic bomb, which was tested for the first time in 1960 in the nuclear test Gerboise Bleue.

Bertrand Goldschmidt was born in Paris on 2 November 1912 to a French mother and a Belgian father of Jewish origin.

He joined the School of Physical Chemistry of Paris in 1932 and was recruited to the Radium Institute in 1933 by Marie Curie. He obtained his doctorate in 1940.

During World War II, he served in a military laboratory in Poitiers and was taken prisoner by the invading Germans who later released him allowing entry into the free zone. He taught for a short time in Montpellier until the post surrender Vichy French government changed the status of Jews under pressure from the Germans. He then emigrated to the United States and arrived in New York in May 1941 where he joined the Free French Forces.

Enrico Fermi later asked Goldschmidt to join him at Columbia University as one of the group of scientists working on the project which would later initiate the world's first man-made self-sustaining nuclear chain reaction in the Chicago Pile-1 experimental reactor. Despite the decision of the U.S. government to refuse the participation of French scientists, Goldschmidt was permitted to join the group in July 1942. He would be the only French citizen to participate in the Manhattan Project on American soil. He worked in the group of Glenn Seaborg, on the development of the PUREX process for separation of plutonium and uranium and was involved in the extraction of the first gram of plutonium produced in Chicago Pile-1.

He later joined the Anglo-Canadian nuclear program (group of Montreal) in Canada where he joined other Frenchman such as Hans von Halban, Jules Gueron, Pierre Auger, and Lew Kowarski who would join the project in 1944. They contributed to the development of Canada's first nuclear reactor, ZEEP diverges in September 1945. He returned to France in 1946 .
