Collector Notes: This watch belonged to Arthur Erich Haas, an Austrian physicist who pioneered a new approach in early quantum theory.' Dr. Haas fled to Ameri- ca from the University of Vienna in fear of Nazi Germany. With a recommendation let- ter from Albert Einstein, Dr. Haas became a professor at Notre Dame University until his death in 1941. The watch was passed down to his younger son and daughter-in-law, the late Dr. George A. Haas and Mary Jane Haas, who lived in Alexandria, Virginia. The Haas family who owned this watch may have been related to the maker, although we do not have clear evidence of this, 13 Michael Wiescher, Arthur E.
