Thérèse Brenet was a French composer and pedagogue whose catalogue of about eighty works ranged across piano music, chamber scores, concertos, symphonic poems and vocal music. Born in Paris on 22 October 1935, she trained at the Conservatoire de Reims and from 1954 at the Conservatoire de Paris, where her teachers included Maurice Duruflé, Noël Gallon, Henri Dutilleux, Darius Milhaud and Jean Rivier. In 1965 she won the Premier Prix de Rome for the cantata Les Visions prophétiques de Cassandre, following a deuxième second prix in 1963 for Les Hommes sur la terre.
The Rome prize took her to the Villa Médicis from 1966 to 1969. She also studied in Poland, including with Witold Lutosławski. Her early oratorio Clamavit, commissioned by French radio and later chosen to represent France at UNESCO's International Rostrum of Composers, travelled widely abroad. Sidérales (1970), for orchestra with a Lucretian text, became another emblematic score, ending with a theme marked perdendosi as if the music continued beyond the page.
From about 1970 she taught at the Conservatoire National Supérieur de Musique de Paris, succeeding Pierre Lantier as professor of solfège in 1971 and remaining until she retired in 2000 to concentrate on composition. Pupils associated with her studio include the violinist Luc Héry, the composer Dominique Probst and the saxophonist and composer Paul Wehage. Outside the classroom she received the Prix Stéphane Chapelier-Clergue-Gabriel Marie of SACEM in 1971 and the Médaille d'Argent de la Ville de Paris in 1973.
Brenet's language moved freely between tonal, atonal and aleatory writing, sometimes using quarter tones and extended instrumental techniques, and she wrote repeatedly for instruments outside the standard orchestra, notably the Celtic harp. Astronomy, nature, literature and religion run through titles such as Chimères, 5523 Luminet PH 8 and Le Livre de l'Harmonie du Monde. Recordings and publisher catalogues have kept a selection of those scores available to performers. She shared a family home in Paris's 16th arrondissement with her sister Antoinette, a professor of Classics. She died in Paris during the night of 5 to 6 September 2026, aged 90. Music press across France and abroad marked her death as the loss of a Prix de Rome voice who had taught for three decades at the Conservatoire.
