Actually brightoffski is correct. There were three members of the Bach family to impact largely on classical music.
Carl Philipp Emanuel Bach (1714-1788),
Johann Christian Bach ((1735-1782),
and the great Johann Sebastian Bach (1685-1750).
The former two were sons of the more well known member of the dynasty.
My personal favourite composer is Tchaikovsky. The power and grandiosity of the Russian, juxtaposed with the subtle beauty of the quieter passages, is brilliant as far as I'm concerned.
