was Henry Willis. The manner in which the organ for St. George's Hall, Liverpool was planned and constructed marks the transition from what Nicholas Thistlethwaite calls the "insular movement" of the 1840s to the adoption of the established German system. Planning formally started on the organ in 1845: the main advisor to Liverpool Corporation was Samuel Sebastian Wesley, son of Samuel Wesley and an accomplished organist, particularly of Bach. He worked in consultation with a panel of university professors of music, who often disagreed with his eccentric suggestions. When Wesley tried to argue about the range of manual keyboards, justifying himself by the possibility of playing octaves with the left hand, he was reminded by the professors that the use of octaves was more common among pianists than first-rate organists and moreover that when he had been organist at Leeds Parish Church, "the dust on the half-dozen lowest keys on the GG manuals remained undisturbed for months." Willis was commissioned to build the organ only in 1851, after he had impressed the committee with the organ for Winchester Cathedral he had on display at The Crystal Palace during the Great Exhibition. The completed organ had four manual keyboards and a thirty key pedalboard, with 17 sets of pedal pipes and a range from CC to f. The instrument had unequal temperament and, as Wesley had stipulated, the air supply came from two large underground bellows powered by an eight horse-power steam engine. Among the innovations introduced by Willis were the cylindrical pedal-valve, the pneumatic lever and the combination action, the latter two features being adopted widely by English organ builders in the second half of the 19th century. The organ was inaugurated in 1855 by William Thomas Best, who later that year was appointed resident organist, attracting crowds of thousands to hear his playing. In 1867, he had the organ retuned to equal temperament. He remained in his post until 1894, giving performances elsewhere in England, including at the Crystal Palace, St James's Hall and the Royal Albert Hall. The St Anne prelude and fugue BWV 552 was used by Best to start off the series of Popular Monday Concerts at St James's Hall in 1859; and later in 1871 to inaugurate the newly built Willis organ in the Royal Albert Hall, in the presence of Queen Victoria. France In France, the Bach revival was slower to take root. Before
