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. [1] [2]


Life and career

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. In 1943 his parents were deported to a concentration camp by the German occupiers of the Netherlands and were murdered there. [3]

Goudsmit studied physics at the University of Leiden under Paul Ehrenfest, [4] where he obtained his PhD in 1927. [5] After receiving his PhD, Goudsmit served as a Professor at the University of Michigan between 1927 and 1946. 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. [6] He was also the scientific head of the Alsos Mission and successfully reached the German group of nuclear physicists around Werner Heisenberg and Otto Hahn at Hechingen (then French zone) in advance of the 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. 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.

After the war he was briefly a professor at Northwestern University, and from 1948-1970 was a senior scientist at the Brookhaven National Laboratory, chairing the Physics Department 1952-1960. He meanwhile became well known as the Editor-in-chief of the leading physics journal Physical Review , published by the American Physical Society. In July 1958 he started the journal Physical Review Letters , [8] which offers short notes with attendant brief delays. [9] 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.

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. [10]

Goudsmit became a corresponding member of the Royal Netherlands Academy of Arts and Sciences in 1939, though he resigned the next year. He was readmitted in 1950. [11]

Felix Bloch Swiss physicist

Felix Bloch was a Swiss-American physicist and Nobel physics laureate who worked mainly in the U.S. He and Edward Mills Purcell were awarded the 1952 Nobel Prize for Physics for "their development of new ways and methods for nuclear magnetic precision measurements." In 1954–1955, he served for one year as the first Director-General of CERN. Felix Bloch made fundamental theoretical contributions to the understanding of electron behavior in crystal lattices, ferromagnetism, and nuclear magnetic resonance.

Werner Heisenberg German theoretical physicist

Werner Karl Heisenberg was a German theoretical physicist and one of the key pioneers of quantum mechanics. He published his work in 1925 in a breakthrough paper. In the subsequent series of papers with Max Born and Pascual Jordan, during the same year, this matrix formulation of quantum mechanics was substantially elaborated. He is known for the uncertainty principle, which he published in 1927. Heisenberg was awarded the 1932 Nobel Prize in Physics "for the creation of quantum mechanics".

Wolfgang Pauli Austrian physicist, physics Nobel prize laureate

Wolfgang Ernst Pauli was an Austrian theoretical physicist and one of the pioneers of quantum physics. In 1945, after having been nominated by Albert Einstein, Pauli received the Nobel Prize in Physics for his "decisive contribution through his discovery of a new law of Nature, the exclusion principle or Pauli principle". The discovery involved spin theory, which is the basis of a theory of the structure of matter.

Linus Pauling US scientist, Nobel laureate

Linus Carl Pauling was an American chemist, biochemist, chemical engineer, peace activist, author, and educator. He published more than 1,200 papers and books, of which about 850 dealt with scientific topics. New Scientist called him one of the 20 greatest scientists of all time, and as of 2000, he was rated the 16th most important scientist in history. For his scientific work, Pauling was awarded the Nobel Prize in Chemistry in 1954. For his peace activism, he was awarded the Nobel Peace Prize in 1962. He is one of four individuals to have won more than one Nobel Prize. Of these, he is the only person to have been awarded two unshared Nobel Prizes, and one of two people to be awarded Nobel Prizes in different fields, the other being Marie Curie. He was married to the American human rights activist Ava Helen Pauling.

Robert S. Mulliken

Robert Sanderson Mulliken was an American physicist and chemist, primarily responsible for the early development of molecular orbital theory, i.e. the elaboration of the molecular orbital method of computing the structure of molecules. Mulliken received the Nobel Prize for chemistry in 1966 and the Priestley Medal in 1983.

Abraham Pais Dutch-American physicist and science historian

Abraham Pais was a Dutch-American physicist and science historian. Pais earned his Ph.D. from University of Utrecht just prior to a Nazi ban on Jewish participation in Dutch universities during World War II. When the Nazis began the forced relocation of Dutch Jews, he went into hiding, but was later arrested and saved only by the end of the war. He then served as an assistant to Niels Bohr in Denmark and was later a colleague of Albert Einstein at the Institute for Advanced Study in Princeton, New Jersey. Pais wrote books documenting the lives of these two great physicists and the contributions they and others made to modern physics. He was a physics professor at Rockefeller University until his retirement.

Erich Schumann was a German physicist who specialized in acoustics and explosives, and had a penchant for music. He was a general officer in the army and a professor at the University of Berlin and the Technical University of Berlin. When Adolf Hitler came to power he joined the Nazi Party. During World War II, his positions in the Army Ordnance Office and the Army High Command made him one of the most powerful and influential physicists in Germany. He ran the German nuclear energy program from 1939 to 1942, when the army relinquished control to the Reich Research Council. His role in the project was obfuscated after the war by the German physics community's defense of its conduct during the war. The publication of his book on the military's role in the project was not allowed by the British occupation authorities. He was director of the Helmholtz Institute of Sound Psychology and Medical Acoustics.
