"Cambridge University Library has taken delivery of the personal archive of musician, broadcaster and writer Deryck Cooke (1919-1976). Musicologist Cooke is perhaps best known for his 1959 book The Language of Music and his work on a 'performing version' of the unfinished draft of Mahler's 10th Symphony, the first version of which was performed at the 1964 Proms. The material has been donated to the Library by Hazel Hyde, who was Cooke's partner for the last six years of his life and has kept the collection intact since his sudden death at the age of 57. The collection contains materials relating to all aspects of Cooke's life and work, including juvenilia and documents from his student days at Selwyn College, Cambridge as well as his service in the Royal Artillery during World War Two. The majority of items, however, relate to Cooke's activities as a writer and broadcaster between 1947 and 1976"
