Fuzzy sets and fuzzy logic in Austria

We sketch the development of fuzzy sets and fuzzy logic in Austria during the last 50 years which started, after some early traces, in 1976 in Linz with my own work and in Vienna with Klaus-Peter Adlassnig’s work. Therefore we first discuss the history of our research group at the Johannes Kepler University Linz and at the JKU-Softwarepark Hagenberg. Next we have a closer look at the developments at the Vienna University Medical School (group of Klaus-Peter Adlassnig), at the logic group at the Vienna University of Technology (in particular the contributions of Agata Ciabattoni), and at the work of Reinhard Viertl in statistics. Finally we present some achievements made at the University of Innsbruck (Michael Oberguggenberger).
