Adler, Guido - Autograph Letter Signed 1894

Austrian musicologist and writer (1855-1941). Autograph letter in German (sold untranslated) signed by him and dated April 1, 1894, to Albert Schatz, concerning music literature. Size is 5.4 x 8.5 inches, 3 written pages, overall rust stains, in very good condition.  Envelope included. Albert Schatz (1839-1910) was a German music dealer with a lifelong interest in opera and its history. In 1873, when Schatz assumed ownership of the Musikalienhandlung Ludwig Trutschel Nachfolger in Rostock, Germany, he confirmed his intent to write a comprehensive history of opera through the study of primary sources. Research for the book necessitated extensive travel throughout Europe to collect libretti including many first and early Italian, German, and French editions from the 17th and 18th centuries: in the end, his collection totaled 12,000 operatic and 238 oratorio and cantatas librettos.
