Gustav Theodore Holst (1874-1934) was an English composer. He is most famous for his orchestral suite The Planets. Holst was into astrology, a hobby that was to inspire the later Planets suite. He read astrological fortunes until his death, and called his interest in the stars his "pet vice". Holst and wife Isobel bought a cottage in Thaxted, Essex and, surrounded by medieval buildings and ample rambling opportunities, he started work on the suite that would become his best known work, the orchestral suite The Planets. (The theme from "Jupiter" has been adapted as a hymn tune under the name of "Thaxted", and is usually sung to the words "I Vow to Thee My Country".)
