Röntgen, Wilhelm Carl (1845–1923)


Wilhelm Roentgen
German physicist, recipient in 1901 of the first Nobel Prize in Physics for his discovery of X-rays. This discovery was made in 1895 when by chance he noticed that a phosphor screen near a vacuum tube through which he was passing an electric current fluoresced brightly, even when shielded by opaque cardboard.

The röntgen unit is named after him.
