Manhattan Project people

Giovanni Rossi Lomanitz (10 October 1921 – 31 December 2002) was an American physicist.

Stanley Phillips Frankel (1919 – May, 1978) was an American computer scientist. He worked in the Manhattan Project and developed various computers as a consultant.

Wilfrid Rall (August 29, 1922 - April 1, 2018) was a neuroscientist who spent most of his career at the National Institutes of Health. He is considered one of the founders of computational neuroscience, and was a pioneer in establishing the integrative functions of neuronal dendrites. Rall developed the use of cable theory in neuroscience, as well as passive and active compartmental modeling of the neuron.
Rall studied physics at Yale University, from which he graduated with highest honors in 1943, and where he was Chairman of the Yale Political Union's Labor Party. He was involved with the Manhattan Project at the University of Chicago during the war, and subsequently worked with K.S. Cole at Woods Hole. He then moved to the University of Otago in Dunedin to work with John Carew Eccles for his PhD, and remained there after Eccles' departure for Australia. In 1954, he spent a sabbatical year at University College London in the Biophysics Department headed by Bernard Katz, and after a final year in Dunedin (where he was Acting Head of Department) he then moved to Bethesda, Maryland and the National Institutes of Health, where he remained until his retirement in 1994.

Nicholas Monroe Smith Jr. (1914 – 2003) was a nuclear physicist and research consultant. Smith was an expert on reactor physics, a developer of operations research/computer modeling, and a computer applications consultant. He had ties to the Manhattan Project at Chicago and Oak Ridge, and worked with Samuel Allison and James Van Allen. Smith was a pioneer in the field of operations research.

Clair Cameron Patterson (June 2, 1922 – December 5, 1995) was an American geochemist. Born in Mitchellville, Iowa, Patterson graduated from Grinnell College. He later received his Ph.D. from the University of Chicago and spent his entire professional career at the California Institute of Technology (Caltech).
In collaboration with George Tilton, Patterson developed the uranium–lead dating method into lead–lead dating. By using lead isotopic data from the Canyon Diablo meteorite, he calculated an age for the Earth of 4.55 billion years, which was a figure far more accurate than those that existed at the time, and one that has remained largely unchallenged since 1956.
Patterson first encountered lead contamination in the late 1940s as a graduate student at the University of Chicago. His work on this subject led to a total re-evaluation of the growth in industrial lead concentrations in the atmosphere and the human body, and his subsequent activism was seminal in the banning of tetraethyllead in gasoline and lead solder in food cans.

Robert Haig Weitbrecht (1920-1983) was an engineer at SRI International and later the spin-off company Weitbrecht Communications who invented a type of a modem (a form of acoustic coupler).

Charlotte Serber (née Leof; July 26, 1911 – May 22, 1967) was an American journalist, statistician and librarian. She was the librarian of the Manhattan Project's Los Alamos Laboratory during World War II, and the laboratory's only female group leader. After the war she attempted to secure a position as a librarian at the Radiation Laboratory in Berkeley, but was rejected for lack of a security clearance; the likely reason was due to her political views. She later became a production assistant for the Broadway Theatre, and an interviewer for Louis Harris.

Heinrich Gerhard Kuhn (10 March 1904 – 25 August 1994) was a British physicist. A graduate of the University of Göttingen, where he studied for his doctorate under the direction of James Franck, winner of the 1925 Nobel Prize for Physics, he left Germany after the Nazi Party came to power there in 1933, and moved to Britain, where relatives had settled, becoming a British subject in 1939. At the invitation of Frederick Alexander Lindemann, he worked for Imperial Chemical Industries at the Clarendon Laboratory in Oxford, where he studied hyperfine structure. During the Second World War, he worked on isotope separation for Tube Alloys and the Manhattan Project. He was the first physicist to become a fellow at Balliol College, Oxford, in 1950, and published textbooks on atomic spectra in German in 1934 and English in 1962.

Bertrand Goldschmidt (2 November 1912 – 11 June 2002) was a French chemist. He is considered one of the fathers of the French atomic bomb, which was tested for the first time in 1960 in the nuclear test Gerboise Bleue.

Taylor Drysdale (January 14, 1914 – February 9, 1997) was an American competition swimmer and swimming coach. Drysdale represented the United States at the 1936 Summer Olympics in Berlin, Germany. He competed in the men's 100-meter backstroke, and finished fourth in the event final with a time of 1:09.4.Drysdale attended the University of Michigan, where he was a member of the Michigan Wolverines swimming and diving team in National Collegiate Athletic Association (NCAA) competition from 1932 to 1935. During his college swimming career, he won three individual NCAA national championships in the 150-yard backstroke (1932, 1934, 1935), and was also a member of Michigan's NCAA-winning teams in the 300-yard medley relay (1932, 1935) and 400-yard freestyle relay (1935).He later earned master's degrees in nuclear physics and mathematics from the University of Michigan, joined the U.S. military, worked on the Manhattan Project, and retired from the U.S. Air Force as a colonel. He was also the manager of the 1956 U.S. Olympic swim team.Drysdale was inducted into the International Swimming Hall of Fame as an "Honor Pioneer Swimmer" in 1994. He died in 1997; he was 83 years old.
