Starting in 1911, General Electric marketed lamps using the new metal and they soon became an important source of income for GE. He also invented the first rotating anode X-ray tube. Dr. W.D. Though the principle of X-rays was invented by Roentgen, the application in medical diagnostics is based on Coolidge’s model. Since residual gas molecules in the tube were no longer necessary as the electron source, the Coolidge (or hot cathode) tube could be completely evacuated which permitted higher operating voltages. In 1910 William David Coolidge then invented an improved method of making tungsten filaments. Besides Roentgen, with his 1895 discovery and subsequent studies of X‐rays, perhaps no other individual contributed more to the advancement of X‐ray technology than did Coolidge.
