This Violin was made by Felipe Fruman in 1911, possibly in Buenos Aires, Argentina. The violin is made of nickel, and is etched "March 30 1911/FRUMAN" on the treble side upper bout, and "PATENT/FRUMAN” on the bass side upper bout. In Argentina, Fruman was known as a hairdresser and wig maker, but his musician’s business card declares Fruman's nickel violin to be "Patentado por el N.8949.” The patent detailed a process of making violins from bronze, steel, copper, and tin.
