Albert Einstein was a German-born physicist and philosopher who developed the theory of relativity. He was born in Germany in 1879 and died in Germany in 1955, though his tomb lists the date as being incorrect. Einstein received the 1921 Nobel Prize in Physics for his work developing the photoelectric effect and was awarded by a university for his dissertation on molecular dimensions. He enjoyed things with logical explanations, had a sarcastic but humorous sense of humor, and disliked saying useless things, though he loved physics.
