William Conrad Roentgen (German: William R? Ntgen, 65438+March 27th 0845-65438+February10,0923), a German physicist.
1895, he discovered x-rays, which were applied to clinical medicine the next year and were successful at the same time. Because of this, Roentgen was awarded the first Nobel Prize in Physics in 190 1. To commemorate Roentgen's achievements, X-rays are called Roentgen rays in many countries. This discovery also contributes to the progress of modern medicine.
In addition, the chemical element Rg 1 1 1 is also named after roentgen.

1895, 165438 1 On the night of October 8, Roentgen discovered an unexpected phenomenon: in order to prevent the influence of ultraviolet light and visible light from leaking out of the tube, he sealed the discharge tube tightly with black cardboard. When the experiment was connected with high-voltage current, he found a fluorescent screen coated with barium platinum cyanide1meter away.
He repeated the experiment with rapt attention, removing the screen step by step. Even at about 2 meters, there is still strong fluorescence on the screen. When he took the coated paper to the next room, closed the door, pulled down the curtains, and the screen kept flashing while the pipe was working. Roentgen was convinced that this novel phenomenon had not been observed so far. ?
In the last weeks of 1895, he didn't tell anyone about his observation, whether it was a collaborator or a colleague. Roentgen worked hard to prove that this accidental observation was a definite fact, and then he did experiments with boards, papers and books, which were all transparent to him.
