Sir Joseph Barnby (12 August 1838 – 28 January 1896) was an English composer and conductor.Barnby was born at York, as a son of Thomas Barnby, who was an organist. Joseph was a chorister at York Minster from the age of seven, was educated at the Royal Academy of Music under Cipriani Potter and Charles Lucas, and was appointed in 1862 organist of St Andrew's, Wells Street, London, where he raised the services to a high degree of excellence. It was at St Andrew's that in 1864, Barnby and the choir performed two anthems by Alice Mary Smith; this is believed to be the first time that liturgical music composed by a woman was performed in the Church of England.
