Henryk Hubertus Jabłoński, originally named Helmut Hubertus Degler, was a Polish composer and pedagogue born on November 3, 1915, in Gdańsk, Poland, where he also passed away on October 11, 1989. Coming from a wealthy Gdańsk family with a tradition of amateur music-making, Jabłoński was initially taught violin and piano by family members. He pursued formal music education at the Polish Conservatory of Music in Gdańsk, studying cello and music theory under Kazimierz Wiłkomirski, and later continued his studies with Werner Schramm and Alfred Paetsch.

In 1935, Jabłoński began working with the radio in Gdańsk as a cellist and arranger of popular music. During World War II, he performed as a cellist and pianist in small entertainment ensembles in Gdańsk. Unfortunately, in 1945, his entire compositional output, consisting of over 200 pieces, was destroyed due to the war.

After the war, Jabłoński chose to remain in Poland and legally changed his name to Jabłoński, adopting his grandmother Rozalia's maiden name. He worked as a cellist with the Gdańsk Symphony Orchestra and directed student choirs at the Gdańsk Polytechnic and the Gdańsk Shipbuilding College. From 1947, he collaborated with the Polish Radio Orchestra, writing popular and entertainment music, and in the 1950s, he arranged folk music from the Kashubia region for the Gdańsk radio station.

Jabłoński was a lecturer in composition and orchestration at the PWSM in Gdańsk, now the Stanisław Moniuszko Academy of Music, from 1954 to 1980. His compositional work includes concertos for cello, violin, and piano, two symphonies, the symphonic poem "Dolina milczenia" (1980), the operatic spectacle "Pani Helena" (1973), the ballet "Gdańska noc" (1970), chamber works, and songs. He also composed popular music, including well-known hits such as "Pierwszy siwy włos" and "Zachodni wiatr."

Jabłoński received numerous awards and honors, including the Gold Cross of Merit, the Medal Stolema (1971), and the Mayor of Gdańsk Award in 1975. He was married to Charlotta Gertruda (Kornelia) Treder, with whom he had three sons, including Roman Jabłoński, a distinguished Polish cellist. Henryk Hubertus Jabłoński was buried on October 17, 1989, at the Srebrzysko Cemetery in Gdańsk.
