née Harrison. The Holst family, of mixed Swedish, German and Latvian ancestry, had been in England since 1802 and had been musicians for several generations. Gustav followed this family tradition; while studying at the Royal College of Music (RCM), he met Isobel Harrison, who sang in one of the amateur choirs that he conducted. He was immediately attracted to her, and they were married on 22 July 1901. While attempting to establish himself as a composer, Gustav Holst worked first as an orchestral trombonist, and later as a teacher. In 1907 he held teaching posts at James Allen's Girls' School in Dulwich, and St Paul's Girls' School (SPGS) in Hammersmith, where he was director of music. From 1907 he acted as director of music at Morley College, an adult education centre in the Waterloo district of London. When Imogen was still very small the family moved from Richmond to a small house by the river in nearby Barnes, which they rented from a relative. Imogen's main memories of this house were of her father working in his composing room on the top floor, which she was forbidden to visit, and of his efforts to teach her folk-songs. Schooling Descriptions of Imogen as a small child indicate that she had blue eyes, fair hair, an oval face reminiscent of her father's, and a rather prominent nose inherited from her mother. In 1912, at the age of five, she joined the kindergarten class at the Froebel Institute, and remained at the school for five years. Summers were often spent at the Holsts' rented country cottage at Thaxted in Essex, where Gustav Holst began an annual Whitsun Festival in 1916. In 1917 Imogen began boarding at Eothen, a small, private school for girls in Caterham, where Jane Joseph, Gustav's star pupil from SPGS, taught music. A letter home, dated 17 July 1917, tells of "compertishions, and ripping prizes, and strawberries and cream for tea". At the school, Imogen studied piano with Eleanor Shuttleworth, violin with André Mangeot (described as "topping") and theory with Jane Joseph ("ripping"). Under Joseph's tuition Imogen produced her first compositions—two instrumental pieces and four Christmas carol tunes—which she numbered as Ops. 1, 2, and 3. In the summer term of 1920, she composed and choreographed a "Dance of the Nymphs and Shepherds", which was performed at the school under her direction on 9 July. Imogen left Eothen in December
