A Dictionary of Music and Musicians/Avery, John
AVERY, John. A celebrated organ-builder, who built a number of instruments, ranging between 1775 and 1808. Nothing whatever is known of his life: he died in 1808, while engaged in finishing the organ of Carlisle Cathedral. The organs he is recorded to have built, are—St. Stephen's, Coleman-street, 1775; Croydon Church, Surrey, 1794 (destroyed by fire in 1866); Winchester Cathedral, 1799; Christ Church, Bath, 1800; St. Margaret's Church, Westminster, 1804; King's College Chapel, Cambridge, 1804 (some of the earlier work of Dallam's organ was, no doubt, incorporated in this instrument, but the case is the original one, erected by Chapman and Hartop in 1606); Sevenoaks Church, Kent, 1798; Carlisle Cathedral, 1808.
