Sir John Frederick Bridge CVO (5 December 1844 – 18 March 1924) was an English organist, composer, teacher and writer. From a musical family, Bridge became a church organist before he was 20, and he achieved his ambition to become a cathedral organist by the age of 24, at Manchester Cathedral. After six years there, he was invited to become organist at Westminster Abbey, where he remained for the rest of his career. He instituted several changes to modernise and improve the music-making at the Abbey and organised the music for several state occasions, including two coronations.
