In memoriam of František Balát on the centenary of his birth

This paper is dedicated to the memory of the prominent Czechoslovak ornithologist and phthirapterist Frantiek Balt (22 July 192520 April 1992), who would have celebrated his centenary this year. Both published and unpublished data, and memories from his colleagues and friends are included. In particular, we discuss his work in the field of chewing lice (Phthiraptera) as a leading world expert. His intensive louse collecting and knowledge of their avian hosts, made a great contribution to knowledge of distribution and biology of many European chewing louse species. The origins and a brief description of Balts louse collection is given.
