I thought this was an interesting and sad article on Einstein's romantic life. It's an interview with Dennis Overbye, who wrote a book called Einstein In Love. He talks about Einstein's first wife, Mileva, and how she was also a physics student at the Polytechnic in Zurich. She abandoned her career in physics when she got pregnant and went back home to Serbia, where she gave up the child, because it would have ruined Einstein's career to have an illegitimate kid. They married, and she was a housewife, waiting for him to come home every night so they could discuss relativity. After about 10 years he started having an affair (with his second-wife-to-be, Elsa), and they divorced.
