notes: label: Description
content: This instrument was patented (English Patent #9418) by John M.A. Stroh in London England on May 4, 1899 and manufactured by George Evans & Co. from 1909–1942. John Matthias Augustus Stroh was born in Frankfurt am Main in 1828, and was an apprentice watch and clock maker, who immigrated to England in 1851. In this instrument, the Stroh patent for amplifying a vibrated string is adapted to the violin. Stroh invented many acoustical devices, and the concept of this patent originated from work on the mechanical sound-box of the gramophone. This violin is made of a solid cylindrical body built of two pieces of half-round mahogany, an aluminum shoulder rest, diaphragm and horn, traditional violin neck, pegbox, and scroll of maple, and a dark red-brown varnish.
