The violin playing is apparently not Einstein, but Carl Flesch recorded somewhere between 1905-1936. And here is an interesting article on Einstein's violin playing: https://news.nationalgeographic.com/2... "there are no authenticated recordings of Einstein’s playing". “Music helps him when he is thinking about his theories,” said Elsa, who became his second wife in 1919. “He goes to his study, comes back, strikes a few chords on the piano, jots something down, returns to his study.” (Read "Einstein’s Evolving Universe: Beyond the Big Bang" in National Geographic magazine.)
