Albert Einstein

Einstein wrote to Perrin enthusiastically about Brownian motion. Curie was a good long-term friend and correspondent, Valéry met him several times, Bose and Schrödinger were important collaborators, Zweig (whom he admired) hosted him in Austria and co-signed a petition for arms limitation. Chaplin took Einstein (a fan) to the première of ‘City Lights’, Bohr and he held a long-running debate (they differed about randomness), Mann was a New Jersey neighbour, and Born (a great friend) played Beethoven duets with him. His conversation with Tagore was advertised as “two planets having a chat.”
