Celebrated 19th century collections dominate this London sale, including music, books and manuscripts that have never before been offered on the market; they have all come by descent to their present owners over a period of more than a century. Among these is the remarkable series of letters by Chopin to his friend the cellist Auguste Franchomme (1808-1884), some written from London and Scotland (lots 227-250). Another cache comes from the family of Ignaz Moscheles (1794-1870), including a poem by Heinrich Heine (lot 43) and letters by Beethoven (lot 207) and Mendelssohn (lot 304-312). Perhaps the most famous provenance is that of the Duchesse de Berry (17981870), much of whose collection of literature and Italian opera scores comes in magniﬁcent French bindings bearing her coats of arms (lots 152-204); this is supplemented by the Duchesse's autograph letters & journals, documenting her turbulent life at the courts of Naples and Paris, and her tragic exile in Austria. There are also sumptuously-bound books deriving from another noble European family (lots 119-151) and medical books from the Royal College of Surgeons in Ireland (63-96). The single greatest item in the sale this June is Mahler's copy of his Third Symphony (296), which the composer has covered with autograph revisions, largely putting the work into its definitive form. Two highlights of the Russian section are a very fine copy of Stroganovs Antiquities of the Russian State (Lot 103) and a remarkable series of letters by Marina Tsvetaeva (lot 104). The sale includes a ﬁne selection of ﬁrst editions of music by J. S. Bach, Beethoven, Mozart, Schubert, Verdi and Vivaldi (356-375).
