Dear colleagues., it is with great sorrow that I inform you that Sibe Mardesic passed two days ago in Zagreb, at the age of 90. Although Sibe was not a categorist but a general and algebraic topologist, I am sure that most of you knew his name and possibly his work dedicated from the early 80’s to Shape and Strong Shape Theory. Anyway he was deeply aware of categorical methods as testified by the large amount of his papers, the book <Shape theory, North Holland(1982)> with Jack Segal, finishing with the monumental <Strong shape and homology, Springer (2000)>. He was the first to categorize Borsuk’s Shape theory adopting the “inverse system” approach. Less than one month ago he told me the he was hardly working on a problem concerning products in the strong shape category of topological spaces. For all who had the pleasure and the honor tho know him and to work with him, Sibe leaves a great legacy of mathematical passion and rigour together with a special humanity. He his deeply missed by all his friends and colleagues all over the world. Ciao Sibe, wherever you are now. Luciano Stramaccia [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
