His most substantial gift was to the Beinecke Rare Book and Manuscript Library at Yale, to which he donated an exceptional collection of musical and literary manuscripts. His core collection held more than 2,000 items, including scores by Debussy, Wagner and Verdi.
“These working scores are really important because they show how something evolved from its first appearance through subsequent productions,” Timothy Young, curator of modern books and manuscripts at the Beinecke, said in an interview.
Mr. Koch’s literary donations to the Beinecke included Noël Coward’s diaries, page proofs of parts of Proust’s “Remembrance of Things Past” and the corrected typescript of Henry Miller’s “Tropic of Cancer.” A separate donation was of 50,000 photographs, most of them of celebrities, taken by Jerome Zerbe, the photographer of mid-20th century cafe society.
