A previously unpublished portrait of Fryderyk Chopin has been discovered, according to the Polish Radio. It was discovered by Chopin-enthusiast Swiss physicist Alain Kohler in the living room of another fan of the composer and is likely a reproduction of a daguerreotype taken around 1847. There exist only two other portraits of Chopin, reproductions of which the originals were lost in World War II. The newly discovered photo is now at the Polish Institute in Paris.
