Albert Einstein dies in Princeton, New Jersey. As a theoretical physicist, Albert Einstein created the general and special theories of relativity, a revolutionary development that paved the way for all the rest of modern physics and quite a bit of modern technology. For this he received the 1921 Nobel Prize in physics.
When Adolf Hitler came to power, Einstein had been visiting the United States and refused to return home to Berlin where he taught at the Prussian Academy of Sciences. Einstein's own ideas came to be denounced in Nazi Germany as "Jewish physics," thus helping retard the development of Nazi science and technology.
