In Vienna ‘the heyday of the coffee house was the turn of the nineteenth century when writers like Peter Altenberg, Alfred Polgar, Egon Friedell, Karl Kraus, Hermann Broch and Friedrich Torberg made them their preferred place of work and pleasure. Many famous artists, scientists, and politicians of the period such as Arthur Schnitzler, Stefan Zweig, Egon Schiele, Gustav Klimt, Adolf Loos, Theodor Herzl, Alfred Adler, and even Leon Trotsky were constant coffee house patrons.’
To say the least things did not turn out well for Vienna during the 20th century.
The Turks upon retreating from Vienna left bags and bags of coffee behind which tells that the defeated Turkish army was running on coffee. The Viennese took the bags and bags of coffee into their city and proceeded to develop a coffee culture. The left behind bags of coffee can be seen as a kind of Trojan horse though even Odysseus would have had difficulties thinking that up.
