Quantum physicists

Hans Albrecht Bethe (German pronunciation: [ˈhans ˈbeːtə] ; July 2, 1906 – March 6, 2005) was a German-American theoretical physicist who made major contributions to nuclear physics, astrophysics, quantum electrodynamics, and solid-state physics, and who won the 1967 Nobel Prize in Physics for his work on the theory of stellar nucleosynthesis. For most of his career, Bethe was a professor at Cornell University.During World War II, he was head of the Theoretical Division at the secret Los Alamos laboratory that developed the first atomic bombs. There he played a key role in calculating the critical mass of the weapons and developing the theory behind the implosion method used in both the Trinity test and the "Fat Man" weapon dropped on Nagasaki in August 1945.
After the war, Bethe also played an important role in the development of the hydrogen bomb, although he had originally joined the project with the hope of proving it could not be made. Bethe later campaigned with Albert Einstein and the Emergency Committee of Atomic Scientists against nuclear testing and the nuclear arms race. He helped persuade the Kennedy and Nixon administrations to sign, respectively, the 1963 Partial Nuclear Test Ban Treaty and 1972 Anti-Ballistic Missile Treaty (SALT I).
His scientific research never ceased and he was publishing papers well into his nineties, making him one of the few scientists to have published at least one major paper in his field during every decade of his career, which in Bethe's case spanned nearly seventy years. Freeman Dyson, once his doctoral student, called him the "supreme problem-solver of the 20th century".

Christian Møller (22 December 1904 in Hundslev, Als – 14 January 1980 in Ordrup) was a Danish chemist and physicist who made fundamental contributions to the theory of relativity, theory of gravitation and quantum chemistry. He is known for Møller–Plesset perturbation theory and Møller scattering.
His suggestion in 1938 to Otto Frisch that the newly discovered process of nuclear fission might create surplus energy, led Frisch to conceive of the concept of the nuclear chain reaction, leading to the Frisch–Peierls memorandum, which kick-started the development of nuclear energy through the MAUD Committee and the Manhattan Project.Møller was the director of the European Organization for Nuclear Research (CERN)'s Theoretical Study Group between 1954 and 1957 and later a member of the same organization's Scientific Policy Committee (1959-1972).

Walther Ludwig Julius Kossel (4 January 1888 – 22 May 1956) was a German physicist known for his theory of the chemical bond (ionic bond/octet rule), Sommerfeld–Kossel displacement law of atomic spectra, the Kossel-Stranski model for crystal growth, and the Kossel effect. Walther was the son of Albrecht Kossel who won the Nobel Prize in Physiology or Medicine in 1910.

Georges Lochak (12 February 1930 – 4 February 2021) was a French physicist known for his work on magnetic monopoles.

John Gleason Cramer Jr. (born October 24, 1934) is a professor emeritus of physics at the University of Washington in Seattle, Washington, known for his development of the transactional interpretation of quantum mechanics. He has been an active participant with the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, and the particle accelerator at CERN in Geneva, Switzerland.

Alfred Landé (13 December 1888 – 30 October 1976) was a German-American physicist known for his contributions to quantum theory. He is responsible for the Landé g-factor and an explanation of the Zeeman effect.
