The B. Bolzano honorary medal - the highest recognition of achievements in the mathematical sciences awarded by the Czech Academy of Sciences - was in 2006 awarded to Imre Csiszár, Mathematical Institute of the Hungarian Academy of Sciences, Budapest and to Flemming Topsře, Institute of Mathematical Sciences, University of Copenhagen. The main area of research of both recipients is Information Theory. Among previous recipients of the Bolzano medal we find Kuratowski, Novák, Kurzweil, Sobolev, Flato, Takeuti and Lovász.

The award ceremoney took place at Charles University in connection with "Prague Stochastics 2006" (pictures 1- 2- 3) . After the ceremoney, Topsře gave a plenary address "Between Truth and Description", detailing recent interdisciplinary research obtained in collaboration with Peter Harremoës and related also to research of Csiszár.

Regarding Topsře's connection to the Czech mathematical community this goes back to the seventies and has encountered research groups in general topology, in descriptive set theory (where especially Frolik's winter schools played a significant role) and then the group of scientists working in information theory. Already in the eighties but more intensely in the nineties, Topsře has been leading research infrastructure projects, active in then Czechoslovakia and other countries. These projects were partly funded by the European Union (e.g. via the TEMPUS Programme) and by INTAS.
