Thomas Edison listens to GE inventor William Coolidge during Edison's visit to Schenectady on October 18, 1922. Coolidge is likely telling Edison about his ductile tungsten swaging machine. Coolidge discovered the process from making tungsten ductile, or flexible. Coolidge's discovery led to the use of tungsten as a lamp filament, replacing the carbon filament used by Edison.
