Today, 19 December, marks the 141th anniversary of the birth of Mileva Marić Einstein. But who remembers this brilliant scientist? While her husband, Albert Einstein is celebrated as perhaps the best physicist of the 20th century, one question about his career remains: How much did his first wife contribute to his groundbreaking science? While nobody has been able to credit her with any specific part of his work, their letters and numerous testimonies presented in the books dedicated to her(1-5) provide substantial evidence on how they collaborated from the time they met in 1896 up to their separation in 1914. They depict a couple united by a shared passion for physics, music and for each other. So here is their story.
Mileva Marić was born in Titel in Serbia in 1875. Her parents, Marija Ruzić and Miloš Marić, a wealthy and respected member of his community, had two other children: Zorka and Miloš Jr. Mileva attended high school the last year girls were admitted in Serbia. In 1892, her father obtained the authorization of the Minister of Education to allow her to attend physics lectures reserved to boys. She completed her high school in Zurich in 1894 and her family then moved to Novi Sad. Mileva’s classmates described her as brilliant but not talkative. She liked to get to the bottom of things, was perseverant and worked towards her goals.
