It is well known that Einstein was the father of the famous Theory of Relativity. But do you know it owes a great deal to Marits, Einstein’s former wife?

In 1896, 17-year-old Einstein went to Zurich to study physics. There he met a girl from Hungary. They studied in the same class. The same interest brought the two together and the young man fell in love with Marits. In 1903, when Einstein was 24 years old, he married Marits, who was 4 years older than he.

After their marriage, Einstein devoted himself to the research of the great theory. To give her husband more help, Marits gave up her own work, and became a good wife and assistant. She tried her best to encourage him whenever possible and she was sure that her husband would succeed. They often discussed the theory while walking outside or sitting together in the room. They even discussed it in their letters when one of them was away from home.

In 1914, the Einstein moved to Berlin and settled there. At that time, Einstein’s theory proved to be correct and he had become famous all over the world. Marits was very proud of him and his success. But it was not long before the First World War broke out. Marits as well as her two sons, who were all on holidays in Switzerland, couldn’t come back to Berlin. The war not only stopped Einstein’s work but broke up the warm, happy family. In 1919, Einstein and Marits had to get divorced.

Einstein himself, however, later said that Marits was really an outstanding woman.
