Moriz Reichenfeld worked from 1880 to 1907 at Union-Bank, becoming its Prokurist (authorized signatory) in 1890. Through his relationship to Gisela (Ella) Naschauer, a sister-in-law of Theodor Herzl, he was in close contact with Zionist circles. After Herzl's death in 1904, he was executor of his will and one of the two guardians of his children. After leaving Union-Bank, he lived from his own means and his bank director's pension. He had a porcelain, ceramics and glass collection as well as carpets, silverware and valuable furniture. His asset declaration after the annexation in 1938, which he was obliged to make on account of his Jewish origins, also listed eighty-eight oil paintings, watercolours and prints, as well as five modern bronzes, including works by Max Suppantschitsch, Oskar Larsen, Josef Danhauser, Peter Fendi, Jehudo Epstein, Tina Blau, Albin Egger-Lienz, Adolf Curry, Hans Makart and Egon Schiele. In 1938 and 1939 he sold some of his painting, porcelain and glass collection via the Weinmüller and Dorotheum auction houses in Vienna. He died shortly afterwards on 12 January 1940 in Vienna. None of the auctioned objects have been located to date.
