is a comic-strip character created by the Polish satirist and graphic artist Zbigniew Lengren (1919–2003). His illustrated adventures began appearing in “Przekrój” in 1948, where they ran weekly for over 50 years – a record run in Polish comic strips. Filutek is a lonely, elegant old gentleman, who has an easygoing outlook and reacts good-naturedly to the world around him. His name invokes the Polish word ‘filut’, an old-fashioned word for ‘jokester’ or ‘prankster’. The retired professor spends his time with his dog, Filuś, whose name was picked by readers of the magazine. The amicable Professor Filutek became highly popular in post-war Poland, as the star of a series of cartoon animations and also featuring on holiday postcards. His popularity stretched beyond Poland, and comics featuring him were printed in East Germany, Czechoslovakia, France, the USSR, and China. Since 2005, visitors to the market square in Toruń (where Lengren grew up and spent his childhood) can encounter a sculpture of the dog Filuś, holding the professor’s bowler hat and guarding his umbrella.
