label: Description
content: Henry Green (1860-1914) was an immigrant from England who moved to Hartford, Ct., in 1888 and began making light bulbs and Crookes tubes. After learning of Roentgen’s 1895 discovery of x-rays, Green made an x-ray tube—probably the first such in the United States. John L. Bauer (d. 1906) was an immigrant from Germany who was working with Green by 189y. Both men died of radiation burns.
