On January 27th， 2014， when Frank Almond， the concertmaster at Milwaukee Symphony Orchestra， was nearing his car after a performance， he was shot down by a young guy． While Almond lay on the ground， that guy made away with．his violin． Luckily， the violin was recovered ten days later by the Milwaukee police．
Almond's violin， which dates back to 1715， was actually made by Antonio Stradivari - an Italian violin maker who lived in the 17th century and made nearly 1，000 violins in his lifetime． Around 650 of them still exist today and can fetch anywhere up to ﹩5 million． This particular violin had many illustrious owners from Italian composer Giuseppe Tartini to Polish violinist Karol Lipinski who played it until 1861． Violins made by Antonio Stradivari are known for their richness and purity （纯净） of sound that are unmatched today．
The present-day violin owes （将……归功于） its design to Andrea Amati （1505-1577）， who is widely recognized as the inventor and the earliest recorded violin maker． Cremona， a city of northern Italy， was the birthplace and seat of violin-making for nearly three centuries． While Amati's sons took over the business， it was his grandson Nicoló Amati who perfected the instrument．
Antonio Stradivari's early designs showed his training in the Amati workshops． During 1700-1725， known as his golden period， Stradivari improved on the soundbox design， and introduced an unusual deep red varnish （清漆）， black edging， broad edges and wide corners． Until his very end， he watched over the final touches on every violin while his sons did the hard work of carving． Besides violins， there are a few cellos， violas and guitars to his credit．
Another famous violin maker of Cremona was Giuseppe Guarneri whose grandfather was also a student worker in Nicoló Amati's workshops． Guarneri's creations are supposed to be even better both visually and in sound quality． Only a hundred survive today．
