Popper, Karl - Unended Quest: An Intellectual Autobiography

When I was twenty I became apprenticed to an old master cabinetmaker in Vienna whose name was Adalbert Pösch, and I worked with him from 1922 to 1924, not long after the First World War. He looked exactly like Georges Clemenceau, but he was a very mild and kind man. After I had gained his confidence he would often, when we were alone in his workshop, give me the benefit of his inexhaustible store of knowledge.
