Walker Bleakney

Walker Bleakney (February 8, 1901 – January 15, 1992) was an American physicist, one of inventors of mass spectrometers, and widely noted for his research in the fields of atomic physics, molecular physics, fluid dynamics,the ionization of gases, and blast waves. Bleakney was the chair of the department of physics at Princeton University.
He was the head of the Princeton Ballistic Project during World War II.
Career.
Bleakney graduated from Whitman College in 1924 with a 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, 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). In a team with other Princeton physicists he produced Hydrogen 3 in 1934.
