He was a German-American physicist who developed the social and general theories of relativity and won the Noble Prize for physics for his explanation of the photoelectric effect in 1921. Einstein advanced a series of theories that proposed entirely new ways of thinking about space, time, and gravitation. His theory of relativity and gravitation revolutionized scientific and philosophic inquiry. Einstein died in April 1955 from an abdominal aortic aneurysm. He has requested that his body be cremated but in a bizarre incident, pathologist Thomas Harvey removed his brain during his autopsy and kept it to study and unlock the secret of this genius. After Einstein’s son’s approval, he cut his brains into pieces, and a handful of studies have been conducted on it since the 1980s.
