Albert Einstein was born in Germany in 1879 and worked as a patent clerk after struggling in school. He did some of his most significant work during this time, writing papers on his theories of relativity. He later taught at universities in Switzerland, Germany, and Prague before moving to the US in 1933 to escape Nazi persecution of Jews. Einstein wrote letters warning of the dangers of the atomic bomb and continued working on theories until his death in 1955. He was considered one of the greatest scientists and thinkers.
