5 Facts: X-ray
In 1895, German physics professor Wilhelm Röntgen stumbled upon x-rays while experimenting with Lenard and Crookes tubes. Since Röntgen’s discovery that x-rays can identify bone structures, they have been used for medical imaging. The first use of x-rays under clinical conditions was by John Hall-Edwards in Birmingham, England in 1896, when he radiographed a needle stuck in the hand of an associate.
