Samuel Russell Warren
1874

Updated through online information from Andrew Henderson (September 7, 2025): From the Globe & Mail (Toronto, July 20, 1874): "Latest from London ... the new organ manufactured by Warren & Co., Montreal, for St. Paul's Cathedral here, is being put in position, and will be ready for use by the 28th. It cost $5,000 and is said to be the largest and best west of Montreal."

From Gargoyles & Gentlemen: A History of St. Paul's Cathedral, London, Ontario 1834-1964: "The contract for building an organ with 24 stops was awarded to F. Limprecht by the vestry in April 1850, 'the cost not to exceed £300.' The actual cost of the organ, installed, proved to be £453 15 s." The organ was sold for $1,000 in 1873 when a new organ, costing $5,000 was installed [Ed.: Samuel Warren Co.].

The original organ was built by Charles Summer Warren, of Montréal, in 1871 [Ed.: Elsewhere reported as 1873, cost $5000. Also S.R. Warren & Sons, spec. Charles, were not established until 1879, and Charles is not reported to be involved before that date. It is highly likely the company was operating still as S. R. Warren at this date.]

In 1918, the instrument was rebuilt and enlarged by Karn-Morris/Woodstock, of Woodstock, ON. It was again completely rebuilt, incorporating much of the original pipework, by Casavant Frères, of St Hyacinthe, QC, in 1952/1953. In 1976, they further modified and added to the instrument when the Choir division was moved to the west of the Great division and left unenclosed. A Trompette-en-Chamade was added in 1997 by Guilbault-Thérien, of St Hyacinthe. In 2012, the 1970s Contrabass was replaced by an Open Wood made by C.S. Haskell, of Philadelphia, in the 1920s.
