Positive Organ Company

William's brother, John, founded Casson's Bank in Wales, and young Thomas was sent to work for him.

Lewis, having left Ruthin Grammar School with virtually no qualifications, was apprenticed to an iron foundry in 1891, which included working on pipe organs.

[13] After that, Lewis was transferred to a firm of organ-builders in Shepherd's Bush, Michell & Thynne;[14] Thomas bought in as a partner in 1889.

He spent so much time travelling between the family home in Denbigh and Shepherd's Bush that the Bank asked him to resign.

[15] The 1882 rebuild of the William Hill organ at St Mary's, Denbigh, is attributed to Casson; Bellamy subsequently rebuilt it again in 1909.

[28] A late (1926) 5-stop Casson Positive, still playable, is at the private chapel of St Paul at Stansted House in Sussex.

[29] The chapel has a 3-bay nave; it was designed by Lewis Way but restored by Harry Goodhart-Rendel in 1926, at which point the Casson Positive was installed.

[30] The small size of the Casson Positives also meant that they were well-suited to large churches and cathedrals which needed additional organs.

The Brompton Oratory in South Kensington had a Casson Positive, which was used to accompany small services, sung by clergy only.

[32] A one-manual 8-stop Positive Organ Company instrument was installed in the crypt of St Paul's Cathedral in London in 1900, to commemorate Queen Victoria's 80th birthday the year before.

[34] The Positive Organ Company provided a one-manual 8-stop instrument for use by Westminster Cathedral in 1902 (and possibly another in 1907, details of which are otherwise lost).

An extant, although unplayable, example is the undated Positive Organ Company instrument installed in 1931 in the chapel at Castle Drogo in Devon (now in the care of the National Trust).

[37][38] Another Positive Organ Company instrument was previously at the residence of Henry Wykey Prosser in Andover.

[40] Until 1958 a Positive Organ Company instrument of unknown origin and date was present at the organist Lady Jeans' house in Westhumble in Surrey, but which she then gave to the chapel of ease in the village.

An extant example of that is the organ in the chapel at St Michael's Mount in Cornwall, originally built in 1786 by John Avery and installed in 1791;[43] Casson rebuilt it in 1906.

In 1902 Casson installed a 46-stop organ into William Raeburn Andrew's home at Cathcart House in South Kensington.

[54] Examples in Australia include a 1900 Positive Organ Company instrument at St Luke, Yea, in Victoria,[55] a 1905 instrument at St Andrew, Aberfeldie, also in Victoria (originally installed in a church in Fiji),[56] and Macarthur Anglican School in Sydney.
