A book of operas

Henry Theophilus Finck (22 September 1854 – 1 October 1926) was an American music critic and author. Among "the most prolific and influential critics of his day", he was chief classical music critic of both the New York Evening Post and The Nation from 1881 to 1924. He championed Romantic music, promoting composers such as Liszt, Wagner, Grieg and MacDowell. Along with his contemporaries Richard Aldrich, W.J. Henderson, James Huneker and Henry Edward Krehbiel, Finck is considered part of the 'Old Guard', a group of leading New York–based music critics who first established a uniquely American school of criticism.
