William Charles Retford (1875–1970) and William R. Retford (1899–1960) were English musical instrument bow-makers, working for the firm of W.E. Hill & Sons. Retford is recognized as developing the Hill bow, along with Alfred Hill. William C. Retford was a perfectionist who became known as the best bow craftsman of his time. He created (and was first to use) the fleur-de-lis design on the best quality gold and tortoiseshell bows. In 1964, William C. Retford wrote "Bows and Bowmakers", which offered a new perspective regarding English bows.
