| November 5, 1895: Wilhelm Roentgen discovers x-rays: It all began for Henry Green – and quite a few other people in Hartford, in the US, and around the world – on November 5, 1895, when William Roentgen discovered x-rays, except that it really didn’t. Roentgen didn’t make his discovery public immediately. He first published his findings in the Proceedings of the Wurzburg Physico-Medical Society on December 28, 1896, and he followed that up with a public presentation in January 1896. From there, word spread through newspapers around the globe. The first article appeared in the Courant on January 22, 1896, and that’s when Green’s involvement with x-rays began. According to Green's 1914 obituary in the Hartford Courant, Green's initial interest in x-rays was driven by the use of vacuum tubes to generate x-rays. Green had been working with vacuum tubes as part of his work on incandescent lamps, and he marshaled that experience as he started his own research. His obituary in the American Journal of Roentgenology similarly noted Green's work in incandescent lamps as critical to his early work in x-rays: his work with the lamps gave him access to both the glassblowers and the vacuum pumps that he needed to develop his own vacuum tube for generating x-rays. Shortly after reading about this discovery, Henry Green began experimenting with x-rays. At some point over the next several weeks, he developed a glass tube that enabled him to focus x-rays and launched the next phase of his career. 1/1896 Probably read article in the Courant on x-rays 2/1896 Public demonstrations at Trinity College Date?

No one realized how dangerous x-rays were at first, and early procedures to photograph objects using x-rays required lengthy exposures of up to 45 minutes. Green, along with his fellow roentgenologists, often used themselves as subjects for their x-ray photographs, and Green suffered burns due to his frequent and prolong exposures to x-rays. He was also indirectly exposed to x-rays throughout his researches, as there was no protective gear for early roentgenologists. Unfortunately for Green and his colleagues, one of their collective discoveries about x-rays were how dangerous they were, and many early researchers succumbed to some combination of burns and cancer brought on by x-rays. Green first noticed burns in 1905, and by 1912 his injuries impeded his ability to continue his work. He underwent four operations in 1913 in order to remove cancerous growths from his face, and he endured his final operation in November 1913, during which his left thumb was amputated and glands in his chest and arms were removed. Four months later he died of liver cancer.
