Robert Eugene Marshak (October 11, 1916 – December 23, 1992) was an American physicist, educator, and eighth president of the City College of New York.

Biography

Marshak was born in the Bronx, New York City. His parents, Harry and Rose Marshak, were immigrants from Minsk. He went to the City College of New York for one semester and then "received a Pulitzer Scholarship which provided full tuition and a stipend which allowed him to continue his education at Columbia University."{{cite web|last1=Collections|first1=Special|title=Robert E.

In 1939, Marshak received his Ph.D. from Cornell University. Along with his thesis advisor, Hans Bethe, he discovered many of the fusion aspects involved in star formation. This helped him on his work for the Manhattan Project, in Los Alamos, during World War II. During this time, he developed an explanation of how shock waves work in extremely high temperatures achieved by a nuclear explosion, and these waves are known as Marshak waves.{{Cite web|title=Robert Marshak|url=https://www.atomicheritage.org/profile/robert-marshak|access-date=2020-11-06|website=Atomic Heritage Foundation|language=en}}

Following the war, Marshak joined the University of Rochester Department of Physics, becoming head of the department in 1950.{{Cite book|last1=Henley|first1=Ernest M.|url=http://www.nasonline.org/publications/biographical-memoirs/memoir-pdfs/marshak-robert.pdf|title=Robert Eugene Marshak, 1916-1992|last2=Lustig|first2=Harry|publisher=National Academies Press|year=1999|location=Washington, D.C.|pages=7}}

In 1947, at the Shelter Island Conference, Marshak presented his two-meson hypothesis about the pi-meson, which were discovered shortly thereafter.{{cite book |last=Mehra |first= Jagdish |title=The Beat of a Different Drum: The life and science of Richard Feynman |year= 1994 |publisher=Clarendon Press |location= Oxford, England |isbn= 978-0-19-853948-3 |pages=245–249 }} Three years later, Marshak established the Rochester Conference while chair of the University of Rochester's physics department. This later became known as the International Conference on High Energy Physics.

In 1957, Marshak and George Sudarshan proposed a V-A ("vector" minus "axial vector") Lagrangian for weak interactions, which eventually paved the way for the electroweak theory. This theory was later presented by Richard Feynman and Murray Gell-Mann, which later contributed to each winning a Nobel Prize in Physics. Sudarshan stated that Gell-Mann had learned the theory from him at the Rochester Conference.{{Cite web|date=2018-05-14|title=ECG Sudarshan Missed Out on Physics Nobel Despite Several Nominations.

Feynman acknowledged Marshak and Sudarshan's contribution in 1963 stating that the V-A theory was discovered by Sudarshan and Marshak and publicized by Gell-Mann and himself.Mehra, p. 477.

Marshak was elected to the National Academy of Sciences in 1958, the American Academy of Arts and Sciences in 1961, and the American Philosophical Society in 1983.{{Cite web |title=Robert E.

In 1970, Marshak left Rochester to become president of the City College of New York.{{cite journal|author=Daniels, Lee A.|date=25 December 1992|title=Robert E.

Marshak shared the 1982 J. Robert Oppenheimer Memorial Prize with Maurice Goldhaber.{{cite journal |author= |title=Oppenheimer Prize awarded to Goldhaber and Marshak |journal=Physics Today |volume=35 |issue=9 |date=September 1982 |page=89 |doi=10.1063/1.2915276 |bibcode = 1982PhT....35i..89. }} The next year he served as the president of the American Physical Society, previously having served on its council (1965-1969), as chairman of its Division of Particles and Fields (1969-1970), and as vice-president.Henley and Lustig, p. 18.

Marshak died by accidental drowning in Cancún, Mexico. In addition to Sudarshan, his doctoral students include Susumu Okubo{{Citation needed|date=November 2020}}, Rabindra Mohapatra and Tullio Regge.{{MathGenealogy|id=106484}}
