This Kuffner observatory is his most important surviving legacy. Kuffner named asteroids 242 Kriemhild and 243 Ida, by courtesy of their discoverer Johann Palisa. During the same period, in 1887, Moriz had a representative residence (the Palais Kuffner) built in Ottakring. It quickly became an attraction for Viennese society, culture, and politics. World War I dealt a significant economic blow to the Kuffner family, and essentially ended the era of their sponsorship. Brewery product sales recovered only very slowly, and profits never returned to the levels seen during the "century of the brewers." During the 1880s and 1890s Moriz von Kuffner became one of the leading mountaineers in Austria. As a keen and recognised Alpinist he conquered most of the Alpine four-thousanders, blazing new routes, some of which were later named after him, like the Kuffer Ridge ("Kuffnergrat") on Mont Maudit and the Kuffner Pillar ("Kuffnerpfeiler") on the Piz Palü.p. 35 He was accompanied on most of his expeditions by mountain guides, Alexander Burgener, J. M. Biner (also Biener), J. Furrer, A. Kalbermatten, Cl. Perren, Christian Ranggetiner, E. Rubesoir, J. P. Ruppen and Martin Schocher. Selection of first ascents:  The year 1938 was disastrous for the 84-year-old Moriz von Kuffner in multiple ways. In January his wife Elsa and then in February his eldest son Ignaz died, and he himself fell ill. Moreover, after the "Anschluss" of Austria to the Third Reich the Kuffner family was subjected to the full range of harassments and physical threats which the newly empowered National Socialists could mount against Jewish industrialists. On March 13, 1938 Moriz averted a forceful attempt by a Sturmabteilung to take over the brewery only by placing his single non-Jewish executive - the laboratory director - formally in charge of the company. In a desperate attempt to salvage whatever he could before the family had to leave Vienna, Moriz' son Stephan Kuffner negotiated the sale of the brewery to an "Aryan" industrialist for 14 million Schilling. Although this was much more than Jewish proprietors of comparable assets had to settle for, it represented only a fraction of the brewery's actual valuation at this time.
