X-Ray Tube
notes: label: Description
content: William David Coolidge (1873-1975) was a M.I.T. graduate with a physics Ph.D. from the University of Leipzig who in 1913, while working for the General Electric Research Laboratory, developed a high intensity, hot cathode, fixed anode X-ray tube with a tungsten filament. This example, probably made by the General Electric X-Ray Corporation, has an “XPDF / COOLIDGE / GE / TUBE” inscription. “DF” stands for double focus.
