examples:
Carl David Anderson
United States physicist who discovered antimatter in the form of an antielectron that is called the positron (1905-1991)
Hans Albrecht Bethe
United States physicist (born in Germany) noted for research in astrophysics and nuclear physics (1906-2005)
Niels Henrik David Bohr
Danish physicist who studied atomic structure and radiations; the Bohr theory of the atom accounted for the spectrum of hydrogen (1885-1962)
Max Born
British nuclear physicist (born in Germany) honored for his contributions to quantum mechanics (1882-1970)
Satyendra Nath Bose
Indian physicist who with Albert Einstein proposed statistical laws based on the indistinguishability of particles; led to the description of fundamental particles that later came to be known as bosons
Louis Victor de Broglie
French nuclear physicist who generalized the wave-particle duality by proposing that particles of matter exhibit wavelike properties (1892-1987)
Arthur Holly Compton
United States physicist noted for research on x-rays and gamma rays and nuclear energy; his observation that X-rays behave like miniature bowling balls in their interactions with electrons provided evidence for the quantal nature of light (1892-1962)
Paul Adrien Maurice Dirac
English theoretical physicist who applied relativity theory to quantum mechanics and predicted the existence of antimatter and the positron (1902-1984)
Enrico Fermi
Italian nuclear physicist (in the United States after 1939) who worked on artificial radioactivity caused by neutron bombardment and who headed the group that in 1942 produced the first controlled nuclear reaction (1901-1954)
Richard Phillips Feynman
United States physicist who contributed to the theory of the interaction of photons and electrons (1918-1988)
Otto Robert Frisch
British physicist (born in Austria) who with Lise Meitner recognized that Otto Hahn had produced a new kind of nuclear reaction which they named nuclear fission; Frisch described the explosive potential of a chain nuclear reaction (1904-1979)
Murray Gell-Mann
United States physicist noted for his studies of subatomic particles (born in 1929)
Donald Arthur Glaser
United States physicist who invented the bubble chamber to study subatomic particles (born in 1926)
Gustav Ludwig Hertz
German physicist who with James Franck proved the existence of the stationary energy states postulated by Bohr (1887-1975)
Gerhard Herzberg
Canadian physicist (born in Germany) noted for contributions to understanding the structure of molecules (born in 1904)
Tsung Dao Lee
United States physicist (born in China) who collaborated with Yang Chen Ning in disproving the principle of conservation of parity (born in 1926)
Marie Goeppert Mayer
United States physicist (born in Germany) noted for her research on the structure of the atom (1906-1972)
Lise Meitner
Swedish physicist (born in Austria) who worked in the field of radiochemistry with Otto Hahn and formulated the concept of nuclear fission with Otto Frisch (1878-1968)
Robert Oppenheimer
United States physicist who directed the project at Los Alamos that developed the first atomic bomb (1904-1967)
Wolfgang Pauli
United States physicist (born in Austria) who proposed the exclusion principle (thus providing a theoretical basis for the periodic table) (1900-1958)
Andrei Dimitrievich Sakharov
Soviet physicist and dissident; helped develop the first Russian hydrogen bomb; advocated nuclear disarmament and campaigned for human rights (1921-1989)
Leo Szilard
United States physicist and molecular biologist who helped develop the first atom bomb and later opposed the use of all nuclear weapons (1898-1964)
Edward Teller
United States physicist (born in Hungary) who worked on the first atom bomb and the first hydrogen bomb (1908-2003)
Eugene Paul Wigner
United States physicist (born in Hungary) noted for his work on the structure of the atom and its nucleus (1902-1995)
Hideki Yukawa
Japanese mathematical physicist who proposed that nuclear forces are mediated by massive particles called mesons which are analogous to the photon in mediating electromagnetic forces (1907-1981)
