his first wife - they WERE married - was mileva maric , a SERBIAN physicist. she was the only female at the "univerity" in zurich. they had a child, a little girl lost to history. maric had a pronounced limp, which is why she was at school - her father thought she would never marry. young einstein was smitten by her exotic looks and smarts. later, he became embarrassed by her and he wanted a much bigger life than she. 
 they had worked together from school on into his professional life on this theory. it is a fact she had GREAT input as she was the one who studied it and was far more advanced than he.  he liked to socialize and she was all about study, he left her  - literally walked out and didn't come back - in 1914 and he married his cousin later. when he won the nobel prize he gave all the money - not the  credit of course - to mileva. blood money. she had a hard life, was diagnosed later with schizophrenia and pretty much died a broken person. lots of good documentaries out there.
