February 3 (1809) is the birthdate of composer Felix Mendelssohn. Mendelssohn is another that started young....he began taking piano lessons at six and is said to have performed in public for the first time at age nine. Like Mozart and Schubert, whose birthdates we recently observed, Mendelssohn only lived into his 30s. And he was certainly more than just a composer! He was a pianist, organist and conductor, and is credited with the rediscovery of Bach's music. Hard to imagine there was a time when J.S. Bach's music was almost unknown, but that was true by the time Mendelssohn had come along. Ironically, Mendelssohn's music went the same route for a time in the late 19th and early 20th centuries, but he is now considered one of the great composers of the so-called Romantic era.
