Samuel Goudsmit

Samuel Abraham Goudsmit (July 11, 1902 – December 4, 1978) was a Dutch-American physicist famous for jointly proposing the concept of Electron spin with George Eugene Uhlenbeck in 1925.

Goudsmit was born in The Hague, Netherlands, of Dutch Jewish descent.

He was the son of Isaac Goudsmit, a manufacturer of water-closets, and Marianne Goudsmit-Gompers, who ran a millinery shop.

Goudsmit studied physics at the University of Leiden under Paul Ehrenfest, where he obtained his PhD in 1927.

After receiving his PhD, Goudsmit served as a professor at the University of Michigan between 1927 and 1946.

Goudsmit married Jaantje Logher, in 1927.

In 1930 he co-authored a text with Linus Pauling titled The Structure of Line Spectra.

During World War II he worked at the Massachusetts Institute of Technology.

As scientific head of the Alsos Mission, he successfully reached a German group of nuclear physicists around Werner Heisenberg and Otto Hahn at Hechingen (then French zone) in advance of French physicist Yves Rocard, who had previously succeeded in recruiting German scientists to come to France.

Alsos, part of the Manhattan Project, was designed to assess the progress of the Nazi atomic bomb project.

Their daughter, Esther Marianne Goudsmit was born in 1933 in Ann Arbor, Michigan.

Goudsmit became a corresponding member of the Royal Netherlands Academy of Arts and Sciences in 1939, though he resigned the next year.

In 1943, his parents were deported to a concentration camp by the German occupiers of the Netherlands and were murdered there.

In the book Alsos, published in 1947, Goudsmit concludes that the Germans did not get close to creating a weapon.

He attributed this to the inability of science to function under a totalitarian state and to Nazi scientists' lack of understanding of how to engineer an atomic bomb.

Both of these conclusions have been disputed by later historians (see Heisenberg) and contradicted by the fact that the totalitarian Soviet state produced the bomb shortly after the book's release.

However that statement overlooks the actions of physicist Klaus Fuchs who sent "many intelligence reports directly from Los Alamos".

He was elected to the United States National Academy of Sciences in 1947, the American Philosophical Society in 1952, American Academy of Arts and Sciences in 1964.

After the war he was briefly a professor at Northwestern University, and from 1948 to 1970 was a senior scientist at the Brookhaven National Laboratory, chairing the Physics Department 1952–1960.

He meanwhile became well known as editor-in-chief of the leading physics journal Physical Review, published by the American Physical Society.

He was readmitted in 1950.

In July 1958 he started the journal Physical Review Letters, which offers short notes with attendant brief delays.

Samuel and Jaantje divorced in 1960, and in the same year Goudsmit married Irene Bejach.

Like Goudsmit's parents, Irene's father, a German medical doctor and Berlin public health official, Curt Dietrich Bejach, had been murdered by the Nazis.

He perished at the Auschwitz concentration camp.

Irene and her sister, Helga, left Germany for the United Kingdom as children shortly prior to the outbreak of World War II.

They were evacuated as part of the Kindertransport programme, and lived for seven years in the Attenborough family home.

In 1964 she earned a PhD in Zoology from the University of Michigan, and in 1972 became a Professor of Biology at Oakland University, Rochester, Michigan.

He also made some scholarly contributions to Egyptology published in Expedition, Summer 1972, pp. 13–16 ; American Journal of Archaeology 78, 1974 p. 78; and Journal of Near Eastern Studies 40, 1981 pp. 43–46.

The Samuel A. Goudsmit Collection of Egyptian Antiquities resides at the Kelsey Museum of Archaeology at the University of Michigan in Ann Arbor, Michigan.

On his retirement as editor in 1974, Goudsmit moved to the faculty of the University of Nevada in Reno, where he remained until his death four years later.

She retired in 1995.
