Mileva Maric, Serbian physicist (d. 1948)
Mileva Marić (Serbian Cyrillic: Милева Марић; 19 December 1875 – 4 August 1948), sometimes called Mileva Marić-Einstein (Serbian Cyrillic: Милева Марић-Ајнштајн, romanized: Mileva Marić-Ajnštajn), was a Serbian physicist and mathematician and the first wife of Albert Einstein from 1903 to 1919. She was the only woman among Einstein's fellow students at Zürich Polytechnic and was the second woman to finish a full program of study at the Department of Mathematics and Physics. Marić and Einstein were collaborators and lovers and had a daughter Lieserl in 1902, whose fate is unknown. They later had two sons, Hans Albert and Eduard.
They separated in 1914, with Marić taking the boys and returning to Zürich from Berlin. They divorced in 1919; that year Einstein married again. When he received the Nobel Prize in 1921, he transferred the money to Marić, chiefly to support their sons; she had access to the interest. In 1930, their second son Eduard had a breakdown at about age 20 and was diagnosed with schizophrenia. With expenses mounting by the late 1930s for his institutional care, Marić sold two of the three houses she and Einstein had purchased. He made regular contributions to his sons' care, which he continued after emigrating to the United States with his second wife (Elsa, his first cousin).
