Robert Sedlaczek

After working as a freelance journalist, among others for the magazine Extrablatt, he became press spokesman for the Austrian Chancellor, Bruno Kreisky in 1980, and, later, for Ferdinand Lacina.

Czapka runs an advertising studio in Vienna and illustrated the books published by Amalthea: Österreichisch für Anfänger, Österreich für Fortgeschrittene and Österreichisch fia Fuaßboifäns, as well the quiz games Das neue Österreich Quiz and Challenge Austria released by Ferdinand Piatnik & Sons.

Since the discontinuation of Wiener Zeitung as a daily newspaper in 2023, Sedlaczek has been publishing his regular language columns as a blog.

[4] Sedlaczek is the author of several dictionaries of varieties of Austrian German with Haymon Publishers (Innsbruck).

A fact that has recently led to the formulation of a One Standard German Axiom in academic Germanistik.

Das große Tarock-Buch ("The Big Tarock Book"), written with Wolfgang Mayr and Roland Kronigl, and Die Strategie des Tarockspiels ("The Strategy of the Game of Tarock"), written with Wolfgang Mayr, are regarded as standard German-language works for this family of card games.

From 2005 to 2018, in his Tarock columns in the Wiener Zeitung, he and Wolfgang Mayr gave tactical tips for the variants of Tarock common in Austria; he is currently writing a similar series with his wife Melita for the Oberösterreichisches Volksblatt (Upper Austrian News).
