Julius Ferdinand Blüthner (11 March 1824 - 13 April 1910) was a German piano maker and founder of the Blüthner piano factory.
Blüthner was born in Falkenhain (now Meuselwitz), Thuringia.
Blüthner pianos had an early success at exhibitions, conservatories and the concert stage.
This added a fourth, sympathetic (aliquot) string to each trichord group in the treble to enrich the piano's weakest register by enhancing the overtone spectrum of the instrument.
