German-born physicist Albert Einstein is widely known as one of the greatest minds that ever lived. During his illustrious career, he developed the theory of relativity, invented the world's most famous equation and managed to reach stratospheric levels of fame unlike any other scientist before him.
His life undoubtedly left an indelible mark on both science and popular culture with his name and image becoming virtually synonymous with genius.
