label: Description
content: Henry Green (1860-1914) was born in England, moved to the United States, and became an electrician. In the 1890s, inspired by Roentgen's discovery of X-rays, Green made an X-ray machine, perhaps the first in the U.S. John L. Bauer (1872-1908) was born in Germany and brought to the United States as a young child. In 1894, now an expert glass blower, Bauer moved to Hartford and began making light bulbs for the Aetna Electric Co. That firm failed in 1898 and was taken over by Henry Green. Working together, Green and Bauer developed an X-ray tube with an angled target, and a regulator for x-ray machines. They also formed a partnership for the manufacture of x-ray apparatus.
