Jerzy "Duduś" Matuszkiewicz (; 10 April 1928 – 31 July 2021) was a Polish jazz musician and composer, playing saxophone, clarinet and piano. Between 1950 and 1958, he was leader of the jazz group Melomani. From 1965, he focused on composing music for films. He was a pioneer of the post-World War II jazz movement in Poland, regarded as a "Founding Father" of Polish jazz. Life and career Matuszkiewicz was born in Jasło and began playing jazz as a youth. He founded a jazz club at the YMCA in Kraków at age 20, and played with the orchestra of Kazimierz Turewicz. A club Melomani (music enthusiasts) was founded in 1947 at the Łódź YMCA, a hang-out of nonconformist thinkers during the late 1940s. Musicians of the first years included Marek Szczerbiński-Sart, trumpeter , drummer Witold "Dentox" Sobociński, and Marian and . Matuszkiewicz came to Łódź to study at the new Łódź Film School. He came to the club and joined the sessions. After only a few concerts, the YMCA was closed because the organisation was criticised for "debauching the youth and promoting imperialistic ideology using jazz music" at the end of the year. Matuzkiewicz founded and led a band in 1950, playing saxophones and clarinet with the former players and additionally pianist Andrzej Trzaskowski and bassist Witold Kujawski. Polish musicians were separated from developments of Western jazz, because the Stalinist regime considered jazz music as part of decadent American culture. They had no recordings and publications, therefore they played a repertoire that did not compare to Western standards. Critic Elliott Simon noted: The band was offered space to practise at the Film School, and during the first year, performed informal concerts at the Film School, in bars and afor private events, around once a week. When they received an invitation to play a concert in Warsaw at the Academy of Fine Arts, they named themselves Melomani. In 1952, pianist Krzysztof Komeda, who had connections and made more concerts beyond Łódź possible, joined the band. They played at the first jazz festival in Sopot in 1956. On 1 January 1958, they were the first Polish jazz band invited to perform at the National Philharmonic in Warsaw. The group disbanded that year. Until 1964, Matuszkiewicz performed both in Poland and abroad. In 1965, he began to mainly compose and conduct music for movies and commercials. He later resided with his wife, Grażyna,
