For this achievement, Einstein is often regarded as the father of modern physics and one of the most prolific intellects in human history.[2][3] He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect".[4] The latter was pivotal in establishing quantum theory within physics .  the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole. He was visiting the United States when Adolf Hitler came to power in 1933, and did not go back to Germany, where he had been a p...
