Albert Einstein is the archetypal kooky scientist who was clearly more than a little bit off and yet was brilliant as brilliant could be. Einstein, although a seemingly friendly, intelligent guy had quite a few skeletons in the closet. In 1901, Einstein and his first girlfriend, Mileva Maric, were on holiday in Italy. It ended when Mileva found herself with child and Einstein found himself with no money to support her and the new baby. The child, Lieserl, was born in 1902 and disappeared from Einsteins letters to Mileva around 1903. Its unknown what happened to the child, but she probably died of scarlet fever.Later in life, Einstein left Mileva in 1912 (and divorced her in 1919) and married his cousin Elsa Lowenthal soon after. In the latter marriage, Einstein had numerous affairs during the marriage and well after Elsas death in 1936. Genius? Yes. Playboy? Definitely.
