Today in our history of innovation...

In 1913, Dr William David Coolidge patented a method for making ductile tunsten for the purpose of making filaments for electric lamps.

When Coolidge joined the General Electric Research Laboratory in 1905, he was given the task of replacing the fragile carbon filaments in electric light bulbs with tungsten filaments, although tungsten was difficult to work. He developed a way to superheat the metal tunsten in order to draw it out into the fine threads used for lamp filaments.
