The history of Fuzziness in Italy is varied and scattered among a num- ber of research groups. As a matter of fact, “fuzziness” spread in Italy through a sort of spontaneous diffusion, and, also subsequently, no one felt the need to cre- ate some “national” common structure like an Association or similar things. Since a cohesive retelling would be next to impossible, a few members of the Italian fuzzy community have been asked to recount their experience and express their hopes (...) for the future.

At the occasion of the fiftieth anniversary of the founding article “Fuzzy sets” by L. A. Zadeh, published in 1965, we briefly outline the beginnings of fuzzy set research in France, taking place some ten years later, pointing out the pioneer- ing role of Arnold Kaufmann and few others in this emergence. Moreover, we also point out that the French counterpart of the name “fuzzy set” had appeared some 15 years before Zadeh’s paper, in a paper written in French by (...) the very person who also invented triangular norms in the 1940’s.

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, at the logic group at the Vienna (...) University of Technology, and at the work of Reinhard Viertl in statis- tics. Finally we present some achievements made at the University of Innsbruck. (shrink)

In this paper, we will briefly look at the history of mathematical fuzzy logic in Czechoslovakia starting from the 1970s and extending until 2009. The role of P. Ha ́jek in the development of fuzzy logic is especially emphasized.

Switzerland is renowned for many things: the mountains, Heidi, chocolate, bank accounts, the punctuality of public transport and, of course, high quality watches. However, Switzerland is probably most famous for exactness and accuracy, influencing Swiss mentalities and everyday life. Legend has it, that is to say, that in Switzerland you can set the watch by the trains – something unheard of in any other European country. Perhaps for this reason, in Switzerland it was especially difficult to take up concepts such (...) as the fuzzy set theory developed by Lotfi Zadeh. Nevertheless, fuzzy set theory found its way into Swiss computer sciences, too, jolting the beliefs and convictions of Swiss scientists. The slightly belated gradual arrival of fuzziness in Switzerland is the topic of this article. (shrink)

Historically, there have been some problems that initially were philosophically posed, either in mystical or in metaphysical terms but that, latter on and step-by-step, were translated into scientific terms and through a process of successive clarifications allowing to arrive, finally, at a scientific theory in which its more essential treats are clearly defined and facilitates its measuring.
