Ferdinand Ries (baptised 28 November 1784 – 13 January 1838) was a German composer. Ries was a friend, pupil and secretary of Ludwig van Beethoven. He composed eight symphonies, a violin concerto, eight piano concertos, three operas, and numerous other works, including 26 string quartets. In 1838 he published a collection of reminiscences of his teacher Beethoven, co-written with Franz Wegeler. The symphonies, some chamber works—most of them with piano—his violin concerto and his piano concertos have been recorded, exhibiting a style which, given his connection to Beethoven, lies between the Classical and early Romantic styles.
