DUSHMAN, SAUL (1883–1954), U.S. chemist and physicist. Dushman was born in Rostov, Russia, and was taken to Canada as a child of nine. He obtained a doctorate at the University of Toronto in 1912 and in the same year joined the General Electric Company Laboratory at Schenectady, n.y., where he worked for 40 years, from 1928 as assistant director. For a period he was also director of research at the Edison Lamp Works. Dushman's published books and papers were mainly concerned with the development and use of high vacuum with which his name is firmly associated. He introduced, with Langmuir, the suffix -tron for equipment in which high vacuum was used; later the suffix was used in words such as cyclotron, magnetron, etc. His books included High Vacuum (1923), The Elements of Quantum Mechanics (1938), Scientific Foundations of Vacuum Technique (1949), and Fundamentals of Atomic Physics (1951).
