Julius Blüthner
From Wikipedia, the free encyclopedia
Julius Ferdinand Blüthner (* 11 March 1824 in Falkenhain Meuselwitz; † 13 April 1910 in Leipzig) was a piano maker and founder of Blüthner piano factory.
In 1853 he founded a piano-manufacturing company in Leipzig Germany. Blüthner pianos had early success at exhibitions, conservatories and the concert stage. Further invention and innovations lead Blüthner to patent a ‘repetition action', and, in 1873, the aliquot scaling patent for grand pianos. 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.
