X-Ray Experiments at Davidson College
On January 12, 1896, three students at Davidson College experimented with x-rays. On January 6, 1896, the Associated Press announced that German physicist Wilhelm Roentgen had discovered a new form of radiation. While experimenting with cathode rays, he discovered that mysterious “x”-rays passed through a variety of objects. He put his hand in front of the rays and saw the silhouette of his bones. At the time, many physics labs had equipment to duplicate the x-ray. Henry Louis Smith, a physics professor and future president at Davidson, was the first professional in North Carolina to work with x-rays.
It was actually a group of Smith’s students who appear to have been the first people in the state to perform x-ray experiments. Three juniors professed to having bribed a janitor to let them into the building housing the physics equipment just six days after Roentgen’s announcement reached America. The students placed objects on photographic paper taking photographs, or what were called roentgenograms, of objects including an eggshell with a button in it, a rubber-covered magnifying glass, a cadaver’s finger, pins, cartridges and paperclips. Years passed before the students’s escapade was made public. The original x-ray images are now housed in the Davidson College Archives.
The experiments are the subject of a highway marker in Mecklenburg County.
