Władysław William "Willy" Wilkanowski (November 15, 1886 in Działyń, Poland – December 8, 1954, Long Island, USA) was a Polish-American violin-maker, guitar-maker and violinist. He was a very productive luthier, known for making over 5000 violins and 100 violas with his staff at his workshop. He also created 30 unique, high-end archtop guitars, one of which, the Wilkanowski Airway W-4, was famously owned by Johnny Cash since the 1980s, when it also was featured as the centerfold in the Guitar World magazine.
