Jesse Wakefield Beams (December 25, 1898[1] inBelle Plaine, Kansas[2] – July 23, 1977[3]) was an American physicist at theUniversity of Virginia. He was particularly known for his role in the development of theultracentrifuge.

Biography

[edit]

Beams completed his undergraduate B.A. in physics at Fairmount College in 1921 and his master's degree the next year at theUniversity of Wisconsin.[2] He spent most of his academic career at the University of Virginia, where he received his Ph.D. in physics in 1925. He spent the next three years in a physics fellowship atYale University, where he performed research on thephotoelectric effect withErnest Lawrence.[4] Beams was appointed a professor of physics at the University of Virginia in 1929 and was chair of the department from 1948 to 1962.[5] During World War II, he worked on theManhattan Project, where his ultracentrifuge was used to demonstrate the separation of the lighter uranium isotope U-235 from other isotopes.[6] Officials in charge of the atomic bomb project concluded, however, that Beams's centrifuges were not as likely as other methods to produce enough highly enriched uranium for a bomb in the time available, and the centrifuge program was abandoned. After World War II, centrifuge separation of uranium isotopes was perfected by German scientists and engineers working in the Soviet Union. In 1953 Beams was appointed the Francis H. Smith Professor of Physics at the University of Virginia. Beams was awarded theNational Medal of Science in 1967 for his work on the ultracentrifuge.[7] He retired from the university in 1969.[8]

Beams' contributions include the firstlinear electron accelerator,[9] the magnetic ultracentrifuge, and the application of the ultracentrifuge to the separation of isotopes and to the separation of viruses from liquids. He held many patents inmagnetic bearings andultracentrifuges. In addition to the National Science Medal, he was awarded theAmerican Physical Society's John Scott Medal, theLewis Award of theAmerican Philosophical Society (of which he was also a member), and the University ofVirginia's first annual Thomas Jefferson Award.[10][11]
