Inghelbrecht entered the Conservatoire at only age seven and studied solfege, harmony and violin. When 16, he was expelled when caught playing violin in local cafes. But soon afterward, he was appointed second violin in the Concerts de l'Opéra orchestra; his friend Pierre Monteux, then conductor of the Concerts Berlioz, would also use him as a substitute – all of which gave him important experience.[2]
During World War II, the ONF was evacuated to Rennes, then Marseilles before its return to Paris in 1943. But when planning the 1,000th performance of the orchestra (which was also to commemorate the 25th anniversary of Debussy's death), Inghelbrecht refused to conduct a program devoted to music of the occupying German forces and on 18 July 1943 received a note suspending his appointment by order of President Laval.[6]
From 1945 to 1950 Inghelbrecht was conductor of the Paris Opéra, and returned to the ONF in 1947. From 1958 to his death in 1965, he prepared weekly radio programs called 'Entretiens autour d'un piano'.
Both in conducting and writing he championed Debussy, Ravel, Roussel, Chabrier and Florent Schmitt.
He corresponded with Debussy – a close friend – from 1911 until the latter's death in 1918. He was a member of Les Apaches along with Ravel, Schmitt and others.
He was married three times: to Colette Steinlen (1910, divorced in 1920), Carina Ari (1928) and Germaine Perrin, with whom he wrote a biography of Debussy in 1953.[6]
Compositions
Although self-taught as a composer, Inghelbrecht left around 60 compositions. The style of his compositions is eclectic. Even when stylistically unoriginal, his polished, masterly orchestration makes his work worthy of closer attention. The operetta Leïla (or Virage sur l’aile) of 1947, is a hilarious comedy and eminently singable entertainment. The opera-ballet Le chêne et le tilleul (after La Fontaine) of 1960 is the climax of the composer's output with harmonies in the style of Debussy contrasting with the Bacchic frenzy of wild dances with pungently rhythmic, virile accompaniment.[7]La Nursery for piano four-hands consists of 36 short pieces composed between 1905 and 1932 and some later orchestrated.
