We know that Isaac Asimov was born Isaak Yudovich Osimov, in Russia, but we don't know exactly when. He was a scientist, trained in biochemistry, but became famous from his writing. Although he wrote nonfiction, including papers and books on science, it was his hard science fiction that made him famous. He is known as one of the Big Three--Arthur C. Clarke and Robert A. Heinlein being the other two--during the Golden Age of Science Fiction.
