The Montreal Mendelssohn Choir was one of the longest-running musical institutions in Montreal in the nineteenth century. Formed in 1864 by eight choristers from Montreal’s Presbyterian community and directed by Joseph Gould (1833-1913), the Choir grew to include sixty-five members by 1880 and over one hundred in the early 1890s. It served as a musical club for the city’s prosperous English merchant and business classes, with an artistic mission that emphasized good singing of unaccompanied part-song repertoire. The Choir disbanded in 1894 and subsequently donated to McGill University the contents of its musical library in addition to 250 volumes of musical literature.
