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 worked with Green.
