Francesc d'A. Sales Vallès
Francesc d'A. Sales Vallès was a professor of Probability and Statistics at the Faculty of Mathematics of the University of Barcelona. From the late 1960s to the 1980s he promoted the study of ordered algebraic structures (lattices, Boolean algebras, etc.) and the study and teaching of mathematical logic in the mathematics curriculum of the university. Many dissertations on related topics were done under his supervision, and this eventually led to the establishment of several research groups in fuzzy set theory, many-valued logic, and algebraic logic, which continue to flourish up to this date and to produce a lot of research in these and neighbouring areas, mainly at the University of Barcelona, at the Polytechnic University of Catalonia, and at the Research Institute on Artificial Intelligence (IIIA-CSIC) based in Bellaterrra (Barcelona, Spain).
