Philipp Lenard

Philipp Eduard Anton von Lenard (; 7 June 1862 – 20 May 1947) was a Hungarian–German experimental physicist who received the Nobel Prize in Physics in 1905 for his work on cathode rays. This work led to his experimental realization of the photoelectric effect, discovering that the energy (speed) of the electrons ejected from a cathode depends only on the frequency, and not the intensity of light.

As an active proponent of the Nazi ideology, Lenard supported Adolf Hitler in the 1920s and was an important role model for the movement during the Nazi period. Notably, he labeled Albert Einstein's contributions to theoretical physics as "Jewish physics". Provided by Wikipedia
