Friedrich Wilhelm Ludwig Grützmacher (1 March 1832 – 23 February 1903) was a German cellist and composer in the second half of the 19th century.
In 1848, he was discovered in Leipzig by the famous violinist, Ferdinand David, who arranged some concerts for him.
He concertized all over Europe and Imperial Russia, where he became a friend of the famous cellist Karl Davydov.
Grützmacher is most famous today for taking samples of four different works to form his edition of Luigi Boccherini's Concerto in B-flat, still being published and performed.
He made frequent tours throughout Europe and Russia as a solo cellist and chamber musician.
