Clarence Dally was born in Woodbridge, New Jersey, one of four brothers. He enlisted in the US Navy at the age of seventeen where he served for six years. After obtaining an honorable discharge he went to work at the Edison Lamp Works in Harrison with his father and brothers as a glassblower. Around 1890 he moved to the Edison Laboratory in West Orange to assist in experiments with the incandescent lamp. Following Röntgen's discovery of X-rays in 1895, Clarence and his brother Charles worked on the development of the Edison X-ray focus tube. At the time, the levels of X-rays produced were not believed to be dangerous, however Edison noted how "the x-ray had affected poisonously my assistant, Mr. Dally." By 1900, Clarence Dally was suffering radiation damage to his hands and face sufficient to require time off work. In 1902, one lesion was on his left wrist was treated unsuccessfully with multiple skin grafts and eventually his left hand was amputated. An ulceration on his right hand necessitated the amputation of four fingers. These procedures failed to halt the progression of his carcinoma, and despite the amputation of his arms at the elbow and shoulder, he died from mediastinal cancer. Following his ordeal, Thomas Edison abandoned his research on X-rays. Woodbridge Township is a township located in Middlesex County, New Jersey. ...
