Johann Caspar Ferdinand Fischer was a German Baroque composer. Johann Nikolaus Forkel, a Baroque-era music theorist, ranked Fischer as one of the best composers for keyboard of his day. However, partly due to the rarity of surviving copies of his music, his music is rarely heard today.
Much of Fischer’s music shows the influence of the French Baroque style, exemplified by Jean Baptiste Lully, and he was responsible for bringing the French influence to German music. Fischer’s harpsichord suites updated the standard model at the time, and he was also one of the first composers to apply the principles of the orchestral suite to the harpsichord, replacing the standard French ouverture with an unmeasured prelude. Both Bach and Handel knew Fischer’s work and sometimes borrowed from it. He lived from September 9, 1656, to August 27, 1746.—Excerpted from Wikipedia
