Charles Emery "Chas E." Farley (1846–1927) was a prominent American violin maker from New Hampshire and Boston, taught by his father, Nathan Farley. He established himself as a full-time luthier in 1883 and became a notable member of the "Boston School" of violin making. Over his career, Farley crafted around 450 high-quality instruments, often using native American woods and classical patterns alongside his own designs. His violins were highly regarded for their rich, vibrant tonal characteristics and distinct warm, reddish varnish. Competing favorably with other leading American makers of his era, his instruments were played by performers in venues like Boston's Symphony Hall. Today, Farley's instruments remain valued by musicians for their craftsmanship and sound.
