One of the amazing things about Antonius Stradivarius is the longevity of his working life.
Born in 1644, Stradivarius' earliest instruments date from about 1670, at age 26. By age 26, Stradivarius was already a well trained luthier with finely honed skills. He kept working and making great instruments until he was 93.
