Pierre Jansen
French film score composer (1930-2015)

Pierre Georges Cornil Jansen (28 February 1930 – 13 August 2015 at Saint-Pierre-Saint-Jean) was a French film scores composer. He was in particular the permanent collaborator of Claude Chabrol for whom he composed the music for many films.
Life
Born in Roubaix, Jansen did his first musical studies at the Conservatoire de Roubaix (piano and harmony) under the direction of Alfred Desenclos. He furthered his studies at the Royal Conservatory of Brussels (piano and harmony prizes) and writing studies with André Souris (harmony, counterpoint, fugue and orchestration).
From 1952 onwards, he regularly attended classes with Olivier Messiaen and participated in the Ferienkurse für die neue Musik in Darmstadt. In 1958, a suite for piano and 18 instruments was premiered in Darmstadt, and later performed in Paris during a concert of the Domaine musical.
In 1960, he renounced the achievements of the avant-garde and devoted himself to film music. He collaborated with Claude Chabrol of whom he became the official composer. About Pierre Jansen, the director of the French New Wave said: "I met a brother in music." while the latter described his meeting with Chabrol as "decisive and unexpected.". He then worked with Claude Goretta, Francis Girod and Pierre Schoendoerffer.
This brief starts where responsible research should: with the source description of “Pierre Jansen” as french film score composer (1930-2015). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as french film score composer (1930-2015). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Nov 28, 2025. The linked authority identifier is Q1570061. VIAF identifies the subject as 117951063. The Library of Congress control number is no96004255. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1930, 2015, 1952 and 1958.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
