William David Coolidge (October 23, 1873-February 3, 1975) was an American physicist. He is a native of Hudson, MA. In the early days of his employment as a researcher for the General Electric Company, he conducted critical experiments that led to the use of tungsten as filaments in light bulbs. In 1913 he invented the Coolidge tube, an improved cathode for use in X-ray machines that allowed for more intense visualization of deep-seated anatomy and tumors.
