Interestingly, the patent office is where Einstein developed many of his world-changing theories. He published in four of them in separate articles in 1905. Soon after publication, Einstein became a household name around the world. The main revelation was his theory of relativity, for which he won the 1921 Nobel Peace Prize. Over the course of 20 years, Einstein held many teaching jobs all over Europe. However, as Nazism gradually took over control of Germany in the 1930s, Einstein wrote and published articles expressing his political views and antipathy for the Nazi party. He soon denounced his German citizenship and left for the US in 1933. His title at Princeton was professor of theoretical physics. Einstein did not want this house to be designated as a museum and has remained a private home ever since.
