Friedrich Wilhelm Grützmacher was a noted German cellist in the second half of the 19th century. He composed mostly for cello (including several concertos and many technical studies), but also wrote orchestral pieces, chamber music, piano music and songs.
Grützmacher is most famous today for taking samples of four different works to form his edition of Luigi Boccherini'sConcerto in B-flat, still being published and performed. He is also known for rearranging J.S. Bach's Cello Suites with additional chords, passages and embellishments. His cadenzas for the cello concertos by Boccherini and Joseph Haydnare often performed to this day. He made frequent tours throughout Europe and Russia as a solo cellist and chamber musician.
