Zbigniew Lengren

was a legendary comic-strip artist for “Przekrój”; a caricaturist who never presented anyone in a malicious way. He invented Professor Filutek, a jolly man dressed in old-fashioned style, with a bowler hat and umbrella. In life, Lengren avoided anything that seemed arrogant or conceited, snobbish or pompous, or demanded too much respect for procedures, hierarchies and obedience.
