Marshall Kay (November 10, 1904 – September 4, 1975) was a geologist and professor at Columbia University.
 He is best known for his studies of the Ordovician of New York, Newfoundland, and Nevada, but his studies were global and he published widely on the stratigraphy of the middle and upper Ordovician.
 Kay's careful fieldwork provided much geological evidence for the theory of continental drift.
 He was awarded the Penrose Medal in 1971.
 Less well known is his work for the Manhattan project, as a geologist searching for manganese deposits.
 Marshall's son Robert Kay of Cornell University and son-in-law Robert Berner of Yale University are also geology professors.
 His son Richard Kay of Duke University is a biological anthropologist and vertebrate paleontologist.
Walter Charles Marshall, Baron Marshall of Goring FRSCBE (5 March 1932 in Rumney, Cardiff – 20 February 1996, in London) son of Frank Marshall and Amy Pearson he studied mathematical physics at Birmingham University and gained a PhD there under Rudolf Peierls.
 In 1955 he married Ann Sheppard in Cardiff and had a son and daughter.
 He joined the Theoretical Physics Division at AERE Harwell in 1954, succeeding Brian Flowers as Head of that Division in 1960 and becoming Director of AERE in 1968; he eventually was appointed Chairman of the United Kingdom Atomic Energy Authority in 1981.
 Appointed a Commander of the Order of the British Empire (CBE) in 1973, he was Knighted in 1982.
 As a champion of nuclear power, he was appointed, in 1983, to be chairman of the Central Electricity Generating Board.
 For his success in keeping the country’s “lights on” during the protracted miners’ strike of 1984-5, Margaret Thatcher rewarded him with a life peerage and he became Baron Marshall of Goring, of South Stoke in the County of Oxfordshire on 22 July 1985.
The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons.
 It was led by the United States with the support of the United Kingdom and Canada.
 From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corps of Engineers.
 Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs.
 The Army component of the project was designated the Manhattan District; "Manhattan" gradually superseded the official codename, Development of Substitute Materials, for the entire project.
 Along the way, the project absorbed its earlier British counterpart, Tube Alloys.
 The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US $2 billion (about $ in 2016 dollars).
 Over 90% of the cost was for building factories and to produce fissile material, with less than 10% for development and production of the weapons.
 Research and production took place at more than 30 sites across the United States, the United Kingdom, and Canada.
Walter Marshall (15 June 1628 – August 1680) was an English, non-conformist Puritan pastor and author best known for his book on the "Gospel Mystery of Sanctification", which has been praised as perhaps the single greatest work on sanctification ever composed.
The B Reactor at the Hanford Site, near Richland, Washington, was the first large-scale nuclear reactor ever built.
 The project was commissioned to produce plutonium-239 by neutron activation as part of the Manhattan Project, the United States nuclear weapons development program during World War II.
 The B reactor was fueled with metallic natural uranium, graphite moderated, and water-cooled.
 It has been designated a U.S. National Historic Landmark since August 19, 2008 and in July 2011 the National Park Service recommended that the B Reactor be included in the Manhattan Project National Historical Park commemorating the Manhattan Project.
 Visitors can take a tour of the reactor by advance reservation.

 Over 90% of the cost was for building factories and producing the fissionable materials, with less than 10% for development and production of the weapons.
Sir Rudolf Ernst Peierls, ( ; ] ; 5 June 1907 – 19 September 1995) was a German-born British physicist who played a major role in Tube Alloys, Britain's nuclear programme, and the Manhattan Project.
 His obituary in "Physics Today" described him as "a major player in the drama of the eruption of nuclear physics into world affairs...".
The Ames Project was a research and development project that was part of the larger Manhattan Project to build the first atomic bombs during World War II.
 It was founded by Frank Spedding from Iowa State College in Ames, Iowa as an offshoot of the Metallurgical Laboratory at the University of Chicago devoted to chemistry and metallurgy, but became a separate project in its own right.
 The Ames Project developed the Ames Process, a method for preparing pure uranium metal that the Manhattan Project needed for its atomic bombs and nuclear reactors. Between 1942 and 1945, it produced over 1000 ST of uranium metal.
 It also developed methods of preparing and casting thorium, cerium and beryllium.
 In October 1945 Iowa State College received the Army-Navy "E" Award for Excellence in Production, an award usually only given to industrial organizations.
 In 1947 it became the Ames Laboratory, a national laboratory under the Atomic Energy Commission.
Walter Marshall (27 October 1853 – 15 January 1943) was an English first-class cricketer active 1889–91 who played for Nottinghamshire.
 He was born and died in Nottingham.
Walter Marshall Browne (16 September 1885 - 6 February 1959) was Archdeacon of Rochester from 1932 to 1951.
