the building in very good stead some three decades after its completion. Famous for its fine claret, numerous members of European society were made welcome there as guests. A total of 15 chefs were employed there, and Alois Hitler Jr., the stepbrother of the future Nazi dictator Adolf Hitler, was a waiter there in the 1920s, before he opened his own restaurant and hotel at Wittenbergplatz, in the western part of the city. Café Josty was one of two rival cafés (the other being the Astoria, later Café Eins A), occupying the broad corner between Potsdamer Strasse and Bellevuestrasse. The Josty company had been founded in 1793 by two Swiss brothers, Johann and Daniel Josty, who had emigrated to Berlin from Sils in Switzerland and set up a bakery from which the café was a 1796 offshoot. It had occupied various locations including (from 1812 till 1880), a site in front of the Berlin City Palace, before moving to Potsdamer Platz in the latter year. A major player on the Berlin café scene, Josty attracted writers, artists, politicians and international society: it was one of the places to be seen. The writer Theodor Fontane, painter Adolph von Menzel, and Dadaist Kurt Schwitters were all guests; Karl Liebknecht, the Spartacus Communist movement leader read a lot here and even made some key political speeches from the pavement terrace, while author Erich Kästner wrote part of his 1929 bestseller for children, Emil und die Detektive (Emil and the Detectives), on the same terrace and made the café the setting for an important scene in the book. Despite the prestige associated with its name, Café Josty closed in 1930. It then went through an odyssey of re-openings, closures and relaunches under a number of different names including Conditorei Friediger, Café Wiener, Engelhardt Brau and Kaffee Potsdamer Platz (sometimes appearing to have two or more names simultaneously), before its eventual destruction in World War II. Among the many beer palaces around Potsdamer Platz were two in particular which contained an extensive range of rooms and halls covering a large area. The Alt-Bayern in Potsdamer Strasse was erected by architect Wilhelm Walther (1857–1917) and opened in 1904. After closing in 1914, it underwent a revamp before reopening in 1926 under the new name Bayernhof. Meanwhile, in Bellevuestrasse, sandwiched between Café Josty and the Hotel Esplanade but extending right through the block with a separate entrance
