Philipp Lenard

Philipp Lenard (1862–1947) was a German physicist known for his work in experimental physics, particularly in the fields of cathode rays and photoelectric effect. He was awarded the Nobel Prize in Physics in 1905 for his investigations into the properties of cathode rays, which were among the first experiments to explore the behavior of electrons. Lenard's research contributed to the understanding of the nature of light and radiation.
