William Gibbons Vowles (usually known as W. G. Vowles or Vowles) (1826 – 25 February 1912) was an English pipe organ maker and refurbisher in Bristol, who established his practice in 1856, although with antecedents dating back to 1753. On his retirement in 1908, the firm was incorporated as W. G. Vowles Ltd. That successor firm was acquired by J. W. Walker & Sons Ltd in 1958. Most Vowles organs were installed in the South West of England.[1]
