Julian Seymour Clifford (London, 28 September 1877 – Hastings, 27 December 1921) was an English conductor, composer and pianist particularly associated with the orchestras at Harrogate and Hastings, which he carried to a high level of accomplishment, introducing new works by English composers and encouraging soloists of national standing to perform in the provinces.
His wife was a soprano singer. After his early death his example was followed by their son, also Julian Clifford (born 1903), who was a composer and a conductor working for Decca Records in early days, and championed works by English composers.
