Robert Hope-Jones (9 February 1859 – 13 September 1914) is considered to be the inventor of the theatre organ in the early 20th century. He thought that a pipe organ should be able to imitate the instruments of an orchestra, and that the console should be detachable from the organ.
Jones was born in Hooton, The Wirral, Cheshire, England to William and Agnes Hope-Jones. He was one of nine children. His younger brother was the horologist Frank Hope-Jones. He started learning the organ at an early age, and by the age of nine, he was playing for occasional services at St Mary's Church, Eastham.
When fifteen he became voluntary organist and choir-master to the Birkenhead School Chapel. Two or three years later he simultaneously held a similar office at St Luke's Church, Tranmere, where he trained a boy choir that became widely celebrated. For this church he bought and set up a fine organ. He subsequently served as churchwarden and was active in many other church offices. He erected an organ in the Claughton Music Hall and organized and conducted oratorio performances in aid of various church funds, training a large voluntary chorus and orchestra for the purpose. For psalms, whose verses are arranged in groups of three, he wrote what he called "triple chants", a form of composition later adopted by other church writers; he also composed canticles, kyries and other music for the services of the church.
He became choirmaster and honorary organist of St John's Church, Birkenhead, doing similar work in connection with that institution. It was at this church and in connection with this organ that Hope-Jones did his first great work in connection with organ-building. The improved electric action, movable console and many other matters destined to startle the organ world, were devised and made by him there, after the day's business and the evening's choir rehearsals. He had voluntary help from choirmen and boys, who worked far into the night, certain of these men and boys later occupying positions with the Hope-Jones Organ Company.
