Einstein was a very frequent guest at Chaplin’s residence. The very thought of the two most brilliant sitting in one room does sound quite impressive, especially because of their unknown intriguing conversations at the time.
Chaplin once said that Einstein was a very calm and pleasant person with an extraordinary intellectual energy and a highly emotional temperament. He also commented on remembering how Einstein’s wife Elsa told him about the time when Albert grasped the theory of relativity. Supposedly, he was acting very peculiar during breakfast one morning and seemed lost in thought. After eating, he went and sat at the piano, played for about half an hour and then disappeared upstairs to study. It was another two weeks before he re-emerged from his room and when he did, the theory of relativity was written down on two sheets of paper.

City Lights (1931), regarded as one of Chaplin’s finest works
The two continued to correspond, and the big public unveiling of their friendship came when Chaplin invited Einstein to the premier of City Lights in 1931 where the mega-celebrities from very different worlds were greeted by reporters, photographers, and adoring crowds. There are several recorded versions of their conversation. In one account, Einstein expressed bemusement at the cheering, and Chaplin remarked, “the people applaud me because everyone understands me, and they applaud you because no one understands you.”
Interesting story- Like the end Paragraph- Makes you Laugh – It would be nice if The book was available- Alas do Not think so.
