Joseph Louis Wilfrid Pelletier (sometimes spelled Wilfred), (20 June 1896 – 9 April 1982) was a Canadian conductor, pianist, composer, and arts administrator.
He was instrumental in establishing the Montreal Symphony Orchestra, serving as the orchestra's first artistic director and conductor from 1935–1941.
He had a long and fruitful partnership with the Metropolitan Opera in New York City that began with his appointment as a rehearsal accompanist in 1917; ultimately working there as one of the company's conductors in mainly the French opera repertoire from 1929-1950.
From 1951–1966 he was the principal conductor of the Orchestre Symphonique de Québec.
He was also a featured conductor for a number of RCA Victor recordings, including an acclaimed reading of Gabriel Fauré's Requiem featuring baritone Mack Harrell and the Montreal Symphony Orchestra and chorus.
Pelletier was one of the most influential music educators in Canada during the 20th century.
It was largely through his efforts that the Conservatoire de musique et d'art dramatique du Québec (CMADQ), an organization which has established and oversees nine different schools of higher education in music and theatre in Quebec, was established in 1942.
From 1943 through 1961 he served as the director of the CMADQ and its first school the Conservatoire de musique du Québec à Montréal.
He also served as the first director of the CMDAQ's second school, the Conservatoire de musique du Québec à Québec, from 1944–1946, and was instrumental in establishing the Conservatoire d'art dramatique du Québec à Montréal in 1954.
As a pianist, Pelletier was active during the 1920s and 1930s as one half of a piano duo with partner Arthur Loesser, the half-brother of Broadway composer Frank Loesser.
The two made a number of recordings together that were made under the direction of Arthur Bodanzky.
He also made a number of solo recordings and Ampico piano rolls in the early 1920s, playing mostly piano reductions from the operas of French composers like Georges Bizet, Charles Gounod, and Jules Massenet.
As a composer, he produced only a small body of work, most notably In the Dark, in the Dew (published in Boston, 1923) which soprano Maria Jeritza included in a number of her recitals.
He was married three times in his life, notably to opera singers Queena Mario and Rose Bampton.
