Swiss-German physicist Albert Einstein (1879-1955, centre) with Dutch physicists Paul Ehrenfest (1880-1933, right) and Pieter Zeeman (left, 1865-1943). Einstein received the 1921 Nobel Prize in Physics for work on the photoelectric effect. However, he is best known for his paper on the special theory of relativity, which resulted in the famous equation E=mc2. Ehrenfest worked on quantum theory and was a contemporary of Einstein, who lauded him as the best teacher of physics he had ever known. He was responsible for the theory of phase transition and the Ehrenfest theorem. Zeeman studied the influence of magnetic fields on light and discovered what is now called the Zeeman Effect, where spectral lines split in the presence of a magnetic field. This.
