Imogen Holst (1907-1984), the only child of Gustav Holst, was a musician of outstanding ability: composer conductor, writer and scholar, she was the first Director of Music in the Arts Department at Dartington in the 1940s; assistant to Benjamin Britten from 1952-64; an Artistic Director of the Aldeburgh Festival, where she was a pioneer of early music; and friend, colleague and inspirer of many eminent musicians. For the last twenty years of her life she devoted much of her time to her father’s legacy, performing recording and editing his music, as well as compiling the definitive Thematic Catalogue of his works for his centenary in 1974.
