May 1, 2023 · Philipp Eduard Anton Lenard (1862–1947), University of Bonn: Passing of cathode rays through thin foils (1894) I am the mother of X-rays. Just as the mid-wife is not responsible for the mechanism of birth, so was Roentgen not responsible for the discovery of X-rays since all the groundwork had been prepared by me.
May 23, 2018 · The cathode–ray work led Lenard to theorize about matter, the basic element of the physical world, and the atoms of which it consists. He concluded that the atom contains neutral pairs of what he called dynamids, one positively charged and the other negatively charged.
The Nobel Prize in Physics 1905. Born: 7 June 1862, Pressburg, Hungary (now Bratislava, Slovakia) Died: 20 May 1947, Messelhausen, Germany. Affiliation at the time of the award: Kiel University, Kiel, Germany. Prize motivation: “for his work on cathode rays”. Prize share: 1/1.
Lenard was the first to cause cathode rays to pass from the interior of a vacuum tube through a thin metal window into the air, where they produce luminosity. Lenard received the 1905 Nobel Prize in Physics for his research in this field.
Philipp Lenard also contributed a great deal to cathode-ray theory, winning the Nobel Prize in 1905 for his research on cathode rays and their properties. Vacuum tubes. The gas ionization (or cold cathode) method of producing cathode rays used in Crookes tubes was unreliable, because it depended on the pressure of the residual air in the tube ...
