20th-century American physicists

John_G._Cramer

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

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.

Robert_B._Leighton

Robert Benjamin Leighton (; September 10, 1919 – March 9, 1997) was a prominent American experimental physicist who spent his professional career at the California Institute of Technology (Caltech). His work over the years spanned solid state physics, cosmic ray physics, the beginnings of modern particle physics, solar physics, the planets, infrared astronomy, and millimeter- and submillimeter-wave astronomy. In the latter four fields, his pioneering work opened up entirely new areas of research that subsequently developed into vigorous scientific communities.

Harvey_Brooks_(physicist)

Harvey Brooks (August 5, 1915 – May 28, 2004) was an American physicist, "a pioneer in incorporating science into public policy",

notable for helping to shape national science policies and who served on science advisory committees in the administrations of Presidents Dwight D. Eisenhower, John F. Kennedy, and Lyndon B. Johnson.

Brooks was also notable for his contributions to the fundamental theory of semiconductors and the band structure of metals.
Brooks was dean of the Division of Engineering and Applied Sciences of the Harvard University.Brooks was also the founder and editor-in-chief of the International Journal of Physics and Chemistry of Solids. He was elected to the National Academy of Engineering "for technical contributions to solid-state engineering and nuclear reactors; leadership in national technological decisions".
He was also Gordon McKay Professor of Applied Physics and Benjamin Peirce Professor of Technology and Public Policy at Harvard University.

Leo_Brewer

Leo Brewer (13 June 1919, St. Louis, Missouri – 22 February 2005, Lafayette, California) was an American physical chemist. Considered to be the founder of modern high-temperature chemistry, Brewer received his BS from the California Institute of Technology in 1940 and his PhD from the University of California, Berkeley, in 1942. Brewer joined the Manhattan Project following his graduate work, and joined the faculty at the University of California, Berkeley in 1946. Leo Brewer married Rose Strugo (died 1989) in 1945. They had three children, Beth Gaydos, Roger Brewer, and Gail Brewer. He died in 2005 as a result of Beryllium poisoning from his work in World War II.

Joseph_Harold_Rush

Joseph Harold Rush (April 17, 1911 – September 12, 2006) was a physicist, parapsychologist and author. He was the first secretary-treasurer of the Federation of American Scientists, and published numerous articles and two textbooks.
Rush was born in Mt. Calm, Texas. In the 1930s his employment as a radio operator in the Dallas Police Department became a way to support his family during the Great Depression. After earning a master's degree in physics, he taught at Texas Technical College in Lubbock and at Denison University. In 1944 he joined the Manhattan Project at the Clinton Engineer Works in Oak Ridge, Tennessee. After the end of the war, he became secretary-treasurer of the Federation of American Scientists, working in Washington to secure civilian control of nuclear power.
Rush received his PhD in physics from Duke University in 1950, and moved to Boulder, Colorado, to work at the High Altitude Observatory of the University of Colorado. He joined the National Center for Atmospheric Research upon its inception, and retired in 1974.
Over his lifetime, Rush authored many articles and books, including The Dawn of Life, a book examining the origins of life on Earth, and Foundations of Parapsychology: Exploring the Boundaries of Human Capability, a textbook on parapsychology.
