Casavant Frčres opus 1239, Saint Joseph Church, Holy Family Parish, Worcester, MA





In 1927 the fifth pastor of Saint Joseph Parish, The Reverend William H. Ducharme, commissioned Casavant Freres of Saint-Hyacinthe Quebec to build an organ for the newly constructed Saint Joseph Church on Hamilton Street in Worcester. The new church and present edifice was the third church building for the parish, the other buildings were on Wall Street.
Little is known about the organs in the previous churches. There is mention in the parish archives of an organ that needed to be hand pumped. The Casavant organ installation was completed for Easter Sunday 1928 just prior to the dedication of the new church building. At the time the organ cost $16,000.
The organ retains its original playing action, console mechanisms and pipe work. In 1973 extensive re-leathering of the pouch rails for the playing action was undertaken and the Grand orgue trompette was replaced with new pipe work. The primary action for the ventils contains the original 1928 leather for most of the stops on the organ. Replacing the 1973 re-leathering and the 1928 leather which is deteriorating has been an ongoing project during the last 12 years.
The organ case was designed by the architect of the church Onesime E. Nault of Worcester who also designed other churches, schools, and convents in New England and Quebec. Dick Brothers of Worcester executed the wood work of the organ case, as well as the wood work for the rest of the church, including pews and confessionals. Casavant supplied the dummy pipes according to Nault's plans.
The present church was dedicated on May 6, 1928. The organist of the Parish, Lucien LaChance, played three organ solos for the dedication: Final de La Premiere Symphonie en Re mineur by Louis Vierne; Pastorale from Dix pieces pour orgue, vol. 2 by Theodore Salome and Fanfare en D. from Ecole d'Orgue, basee sur le plain-chant romain by Jacques-Nicolas Lemmens. Lucien LaChance studied with the noted Canadian pianist, music pedagogue, composer and organist of The Montreal Cathedral, Arthur Letondal (1869-1956). In 1928, parishioner Mrs. Clemence LeClerc initially served as the assistant organist and later became the parish organist. In 1931 she played a concert on the organ featuring works of Bach, Salome, Franck (A minor chorale) and, Gigout. A plaque commemorating her dedicated service to the parish is on the console.












Pipe Organ

Pipe Organ
Maker: Thomas Appleton

The pipe organ is the best preserved product of the renowned Boston craftsman Thomas Appleton. Built in 1830, perhaps for South Church in Hartford, Connecticut, it was reinstalled by Emmons Howard in 1883 at Sacred Heart Church in Plains, Pennsylvania, where it was discovered, unused and neglected, in 1980. The organ's conservative tonal design and mahogany Greek Revival case reflect British models of the late eighteenth century. Standing more than fifteen feet high and having gold-leafed facade pipes (diapasons), the organ comprises sixteen ranks totaling 836 pipes, two 58-tone manuals, and a 27-note pedalboard, the latter replacing the shorter original one. Wind is supplied by hand-pumped bellows. The pipes of the upper manual are mainly enclosed in an elevated box with louvers that can be opened by a pedal for dynamic expression. The rest of the manual pipes are disposed above the recessed console, while the blowing apparatus and the key and stop mechanisms occupy the lower part of the case. The pedal rank rests on a separate wind chest behind the case. Tuning is in a customary mean tone temperament pitched at A=435.7 Hz.

Appleton's carving and joinery are particularly skillful. Before being hired by the prominent organ builder William Goodrich in 1807, Appleton had served an apprenticeship with the cabinetmaker Elisha Larned. Following a partnership with the piano makers Hayt and Alpheus Babcock, Appleton opened his own shop in 1820. In 1839 the Massachusetts Charitable Mechanic Association awarded him a gold medal, and his reputation continued to grow until he retired in 1869, by which time his numerous instruments were serving churches as distant as California and South Carolina.
