Henry Balfour Gardiner (1877–1950) was an English conductor and composer known for his significant contributions to the British music scene in the early 20th century. He primarily worked within the genres of classical and orchestral music, and he played a crucial role in promoting contemporary British composers. Gardiner is best known for his work as the conductor of the London Symphony Orchestra and the Royal Liverpool Philharmonic Orchestra, where he championed the works of prominent composers such as Ralph Vaughan Williams and Gustav Holst. His notable works include the choral pieces "The Ballad of Sir John Franklin" and "The Wreck of the Hesperus," which showcase his melodic style and affinity for vocal music. Gardiner's impact on music lies in his dedication to the performance and promotion of British compositions, helping to establish a national identity in music during a time when English composers were gaining international recognition. His advocacy for new works and emerging composers contributed to the evolution of British classical music in the 20th century.
