Brian Brockless (21 January 1926 – 18 December 1995) was an English composer, organist and conductor and, for much of his life, was the Director of Music at the Priory Church of St Bartholomew-the-Great, Smithfield, London where he succeeded Paul Steinitz in 1961.
He was inspired by music from a very young age along with his sister Pauline, who herself became a fine soprano and performed regularly at the Proms.
Brockless studied organ and composition at the Royal College of Music under the direction of Herbert Howells, a great influence on the young composer.
For twenty years Brockless was a part-time professor at the Royal Academy of Music and was subsequently made an Honorary Member.
As well as conductor and composer, Brockless had a fine counter-tenor voice which he employed along with his sister Pauline in Wigmore Hall recitals, as a choir member of the Savoy Chapel, Schola Polyphonica and the Elizabethan Singers.
