## Bio

Philipp Eduard Anton von Lenard was born on 7 June 1862 in what was then Hungary. His experiments with cathode rays earned him the Nobel Prize in Physics in 1905, and he realized the photoelectric effect experimentally — finding that ejected electron energy depends on light's frequency, not its intensity. In the 1920s he became an active proponent of Nazi ideology and supported Adolf Hitler. During the Third Reich, Lenard served as an important role model for the Deutsche Physik movement, which sought to purge theoretical physics of what he and others labeled "Jewish physics" — a direct attack on Albert Einstein's contributions. He died on 20 May 1947.
