Lubomír Beneš' most significant work was his co-authorship of the animated puppet series, Pat and Mat (THAT'S IT!) with Vladimír Jiránek. This series originated from the film The Tinkerers in collaboration with other major authors. Lubomír Beneš was raised in Prague – Hloubětín, on the outskirts of Prague. Due to his creative talent, his parents paid for private lessons in illustration, painting and calligraphy. After his military service, he was accepted to the Bratři v Triku animated film studio where he was gradually familiarised with the techniques of animated film.
In 1967, Beneš joined the studio of Jiří Trnka, where he shot his first animated film, Man. Lubomír Beneš' first puppet film, Please Excuse Me, was produced in 1974. Since then, he has shot dozens of puppet, cartoon, and animated films at the Kratký Film Praha studio. Together with Vladimír Jiránek and other artists, he founded the IAF studio in 1990, where he continued to create works until his death. Lubomír Beneš passed away in 1995.
