Walter Leigh (1905-42) was a celebrated composer and alumnus of Christ's College, where he matriculated in 1923. He composed in a variety of musical genres: orchestral, chamber, songs, theatre, operetta and revue. He also did a lot of work in Cambridge theatre, composing original music (including 'The Frogs of Aristophanes' at the Arts Theatre, which was revived as the Cambridge University Greek play). He set music for two renditions of Milton's 'Song on May Morning'. He was killed in the War in 1942 and his name is included in the war memorial in the chapel in college.

His grandfather, the Rev. Walter Leigh (1826-1891) was an alumnus of Pembroke College and St Mary's Oxford. He wrote an oratorio of Milton's 'Paradise Lost' and 'Paradise Regained' which were published in 1869 and performed on several occasions. Copies of the full orchestral and musical scores are in the British Library and several musical colleges.
