Lieben, Auspitz, Schey von Koromla, Todesco, Goluchowski-Glochowsky, Wertheimstein, and Wiernes families. In 1830 the Jewish von Neumann family were elevated into the nobility. The elevation into the nobility of wealthy Jews also started the process of assimilation of Jewish families into the Austrian upper class. Abolition of nobility in 1919 With the same date, the Habsburgergesetz of 1919 ("Habsburg Law"), which legally dethroned, exiled and confiscated the properties of the Imperial House of Habsburg, the Adelsaufhebungsgesetz (Arbitration Act) of 3 April 1919 ("Law on the Abolition of Nobility") abolished nobility as well as all noble privileges, titles and names in Austria. In other monarchies of Europe, Austrian noble families may use their noble titles as well as nobiliary particles such as von and zu in their names and they still retain noble status there. For example, the name of the heir to the Austro-Hungarian throne became in Austria simply Karl Habsburg-Lothringen instead of Karl von Habsburg; in Belgium, however, he is known as Archduke Karl of Austria. This may sometimes be confusing, as descendants of nobles are sometimes referred to with noble names abroad. Also, members of noble families often hold multiple citizenships, as was the case for Otto von Habsburg (eldest son of the last Emperor of Austria-Hungary and father of Karl Habsburg-Lothringen), who was also a citizen of Germany. The Austrian law does not apply to artistic, performer or stage names, where von is sometimes used, as in the case of conductor Herbert von Karajan or the musician Hubert von Goisern. However, stage names are never recognized for official purposes. Members of the lower nobility especially (such as civil servants) found this radical step of abolition degrading and humiliating, since working towards and finally earning a noble title was a way for them and their families to rise within society. Members of the higher nobility were able to absorb the formal abolition more easily. They lost their titles and privileges, but kept their social networks, manners, standing and riches. Federal President Michael Hainisch called the official abolition The law abolishing nobility and titles was never repealed, even during the period of Austrofascism (1934–1938). Following the Anschluss to Nazi Germany (1938–1945), this law remained on the books, although it was not enforced, allowing Austrian nobles to use titles freely again. Although noble titles and the particles von and zu are no longer legal, some persons are still unofficially referred
