Albert Einstein (1879-1955) was born in Ulm (Germany) on March 14, 1879. In the 1920s he learned Go while living in Berlin. In the 1930s Einstein shared an apartment with Emanuel Lasker and was a good friend of Edward Lasker, too.
Once Edward Lasker gave Einstein an autographed copy of his book on Go and Chess. Einstein gave Edward a copy of his papers on relativity in return. The book given to Einstein later showed up in an used bookstore. Lasker commented it with: "That's all right. I left his relativity paper on the subway."
