Geoffrey Winzer Gilbert (28 May 1914 – 1989) was an English flautist, who was a leading influence on British flute-playing, introducing a more flexible style, based on French techniques, with metal instruments replacing the traditional wood. He was a prominent member of five British symphony orchestras between 1930 and 1961, and in 1948 he founded a chamber ensemble of leading wind players. After the Second World War Gilbert combined his playing career with teaching, holding appointments at music colleges in London, Manchester, and finally in Florida.
