William S. Haynes first established his name as a flute maker through his dedication to exacting detail in every instrument that left his workshop. Then in 1913, he created a breakthrough in design that set Haynes flutes even more above the rest. This breakthrough, which resulted in a patent, corrected a design flaw that had troubled flutemakers and players up until that time. Through a combination of classic detailed hand-craftmanship and innovation in design and technique, William S. Haynes set a standard that prevails to this day at the flute workshop that still bears his name.
