X-Ray Tube
notes: label: Description
content: William David Coolidge (1873-1975), a physicist working for General Electric, developed the hot cathode glass x-ray tube, described it in the Physical Review (Dec. 1913), and gave demonstrations to physicians and radiologists, many of whom saw the advantages for diagnostic purposes and cancer treatments. When the United States entered World War I, General Electric was asked to develop portable x-ray apparatus for military use. General Electric acquired the Victor X-Ray Corp. in 1920.
