Mileva Marić, sometimes called Mileva Marić-Einstein, was the first wife of Albert Einstein from 1903 to 1919. She was the only woman among Einstein's fellow students at Zürich Polytechnic. Marić and Einstein were study colleagues and lovers, and had a daughter Lieserl in 1902, who likely died of scarlet fever at one and a half years old. They later had two sons, Hans Albert and Eduard. The question of whether she contributed to Einstein's early work has been debated.
