John von Neumann emigrated from Hungary in 1933 and settled in Princeton, NJ. During World War 2, he contributed a key idea to the design of the plutonium bomb at Los Alamos. After the war he became a highly sought-after government consultant and did important work kickstarting the United States’s ICBM program. He was known for his raucous parties and love of children’s toys.
Enrico Fermi emigrated from Italy in 1938 and settled first in New York and then in Chicago, IL. At Chicago he built the world’s first nuclear reactor. He then worked at Los Alamos where there was an entire division devoted to him. After the war Fermi worked on the hydrogen bomb and trained talented students at the University of Chicago, many of whom went on to become scientific leaders. After coming to America, in order to improve his understanding of colloquial American English, he read Li’l Abner comics.
Hans Bethe emigrated from Germany in 1935 and settled in Ithaca, NY, becoming a professor at Cornell University. He worked out the series of nuclear reactions that power the sun, work for which he received the Nobel Prize in 1967. During the war Bethe was the head of the theoretical physics division of the Manhattan Project. He spent the rest of his long life working extensively on arms control, advising presidents to make the best use of the nuclear genie he and his colleagues had unleashed, and advocating peaceful uses of nuclear energy. He was known for his hearty appetite and passion for stamp collecting.
Victor Weisskopf, born in Austria, emigrated from Germany in 1937 and settled in Rochester, NY. After working on the Manhattan Project, he became a professor at MIT and the first director-general of CERN, the European particle physics laboratory that discovered many new fundamental particles including the Higgs boson. He was also active in arms control. A gentle humanist, he would entertain colleagues through his rendition of Beethoven sonatas on the piano.
Von Neumann, Fermi, Bethe and Weisskopf were all American patriots. Read more »
