Professor Guido L. Weiss has had a very wide and interesting career. If one enters "Guido Weiss" in Google, several rather long articles about him will appear. We shall describe them in relatively few words that will give an idea of what he has done mathematically. His CV is very broad. All his university degrees are from the University of Chicago. After graduating with a Ph.D., he was on the faculty of DePaul University from 1956 to 1960. After this, from 1960 to 2015 his positions were all at Washington University in St. Louis. During his fifty-five years period he was very active as a mathematician and performed a considerable amount of research and occupied several academic positions. The list of publications (from 1955 to 2012) contains 121 papers (in one of the Google articles) and has published nineteen more articles and is now cooking two more.
His professional experience and honors are considerable. He received honorary professorships from the University of Milano (Bicocca), in Italy, the University of Barcelona, Spain, the Beijing Normal University, in China; the Chauvenent Prize and other similar prizes.
He has been invited to many lectureships all over the world. In particular he has travelled to China many times since 1980 and has "replaced" many Soviet mathematicians as a professor (nine of his fourty-eight Ph.D. students are from China).
