Walker Bleakney
Walker Bleakney (February 8, 1901–January 15, 1992) was an American physicist,〔(National Academies Press, Biographical Memoirs V.73 (1998), Walker Bleakney by GEORGE T. REYNOLDS )〕 one of inventors of mass spectrometers,〔〔(New York Times:SCIENCE PRODUCES NEW HEAVY WATER; Ten Drops of Tritium Yielded by 'Boiling Down' 75 Tons of Ordinary Water, March 16, 1935 )〕〔(Measuring mass: from positive rays to proteins By Michael A. Grayson, page 133 )〕〔(A New Mass Spectrometer with Improved Focusing Properties, Phys. Rev. 53, 521–529 (1938), Walker Bleakney and John A. Hipple, Jr. )〕 and widely noted for his research in the fields of atomic physics, molecular physics, fluid dynamics,the ionization of gases, and blast waves.〔(Princeton University Library Manuscripts Division:Walker Bleakney Papers, 1920s-1961 )〕 Bleakney was the chair of the department of physics at Princeton University.〔〔(New York Times:PRINCETON WINS HONOR; Physics Laboratory Gets Atomic Safety Award, September 24, 1961 )〕
He was the head of the Princeton Ballistic Project during World War II.〔〔(Declassified military records, NEW LIMITATION CHANGE TO, ADB279629 )〕
== Career ==
Bleakney graduated from Whitman College in 1924 ith BS degree. He received his Ph.D. from the University of Minnesota in 1930.〔
He then spent his entire career at Princeton University, first as a National Research Fellow,〔(New York Times:SPLIT-SECOND SPEED OF RADIUM CLOCKED; New Device Records Passage of Alpha Particles Ten Millionths of a Second Apart,February 27, 1932 )〕 then as an instructor in 1932.〔
He then became an assistant professor in 1935(), an associate professor in 1938 and a full professor in 1944.〔 Bleakney became the chair of the Department of Physics in 1960, and remained in that capacity until 1967.〔
Early in his career at Princeton, Bleaker was able to make a difference in nuclear physics. For example he proved that heavy water contains traces of triple-weight hydrogen (1935).〔(New York Times:THE WEEK IN SCIENCE: MAN BATTLES WITH THE WINDS; Dust Storms Raise Fears That the West May Become a Sahara -- Whence Come Cosmic Rays? -- Boulder Dam's Life;By WALDEMAR KAEMPFFERT, March 31, 1935, )〕 In a team with other Princeton physicists he produced Hydrogen 3 in 1934.〔(New York Times:LAST OF ELEMENTS MADE IN 'QUANTITY'; Princeton Physicists Announce Creation of Hydrogen Three in Tangible Form. FILL GAP IN ATOMIC TABLE Washington Science Session Hears of Synthetic Production From Water.By WILLIAM L. LAURENCE.Special to THE NEW YORK TIMES. April 29, 1934, )〕
