Notes and letters, all addressed to Frederick A. Stock with two exceptions, mostly from musical artists and composers. Of the sixty items, twenty are written in German, several in French, and one in Italian from Ottorino Respighi to a person named "Rossi." Included among the more interesting pieces are letters from Nadia Boulanger, Percy Grainger and Walter Damrosch, and postcards with their photos from Wilhelm Backhaus and Wanda Landowska. Also, a letter in German from Theodore Thomas written in 1904; and a letter from Rose Fay Thomas written in 1905, which describes Thomas's burial and also gives her directive for the maintenance of her husband's musical scores. Other correspondents include John Alden Carpenter, Pablo Casals, Gregor Piatigorsky, Georg Schumann, John Philip Sousa, and Fannie Bloomfield Zeisler. Also includes eight 8x10 black and white photographs of Stock conducting rehearsals at Interlochen Music Camp (Gift of Esko Townell, 2011.)
