John Field: the 18 nocturnes for piano, 75 pages.Wikipedia:
Field was very highly regarded by his contemporaries and his playing and compositions influenced many major composers, including Frédéric Chopin, Johannes Brahms, Robert Schumann, and Franz Liszt. Field is best known as the instigator of the nocturne, but there is evidence to suggest that this is a posthumous accolade. Although little is known of Field in Russia, he undoubtedly contributed substantially to concerts and teaching, and to the development of the Russian piano school.
