There was immediate interest from researchers for the X-ray. A.A. Campbell - Swinton and Nikola Tesla were amongst the firsts to test the new discovery. In 1896, Thomas Edison investigated materials ' ability to fluoresce when exposed to X-rays, and found that calcium tungstate was the most effective substance. Around March 1896, the fluoroscope he developed became the standard for medical X-ray examinations. Nevertheless, Edison dropped X-ray research around 1903, even before the death of Clarence Madison Dally, one of his glassblowers. Dally had a habit of testing X-ray tubes on his hands, and acquired a cancer in them so tenacious that both arms were amputated in a futile attempt to save his life.
