Moreover, when Albert admitted adultery and divorced Mileva in 1919, he promised that in the event he should win the Nobel Prize all the money-not part of the money but all the money-would go to Mileva. According to the Einstein biography, Subtle is the Lord, Einstein kept his promise. When he received the Nobel Prize money in 1922 (he was awarded the prize for the year 1921; the award was announced and he received the money in 1922) Albert did indeed give Mileva all the money from the Nobel Prize. Why all the money?
There are other strange aspects to Einstein's life. Einstein was extremely secretive about his first marriage. It was only in 1987, with the publication of the Love Letters between Albert and Mileva that we find out Einstein fathered a daughter, named Lieserl, the first child of Albert Einstein and Mileva Maric. Nobody really knows what happened to this child; there is a mention in one of the letters to her having scarlet fever and it is believed that the child was put up for adoption in Serbia. Albert never breathed a word about her publicly during his lifetime, which is quite strange.
The Love Letters also make clear that Mileva Maric was absolutely hated by Einstein's mother, Pauline, who protested to her son that Mileva was, "a book like you." Still, despite his mother's fierce objections, Einstein stubbornly went ahead and married her. It was during this marriage that Einstein is credited with producing the 1905 papers which made him famous.
After they married, Mileva bore Albert two more children, sons Hans Albert and Eduard. Eduard suffered psychological troubles throughout his life, and according to Dord Krstic was even seen by Sigmund Freud.
Maric seems never quite willing to take complete credit for the work she did. Much has been made of Maric never having graduated from the Swiss Polytechnic, implying that she could not have been the intellectual equal of Albert Einstein.
