From 1899 to 1905 he was a research assistant to Arthur A. Noyes of the Chemistry Department at MIT. The Coolidge tube (Patent 1,203,495 granted 1916), used for medical and industrial x-ray sciences, was invented and developed in the GE Laboratory, with Dr. Coolidge receiving over three dozens related patents. 1,082,933 for the method of making tungsten filament f… 1926 Howard N. Potts Medal, the Franklin Institute, in considera- tion of the originality and ingenuity shown in the develop- ment of a vacuum tube that has simplified and revolution- ized the production of X-rays. However, in 1928 a US court ruled[2][3][4] that his 1913 patent was not valid as an invention. William David Coolidge had also made notable discoveries and advancement with X radiations.
