Samuel Zygmuntowicz started making violins when he was 13-years-old. Now in his 60s, Zygmuntowicz has worked with many of the finest (and most demanding) violinists in the world—including Isaac Stern, Cho-Liang Lin, Joshua Bell—crafting violins and cellos out of his Brooklyn work shop. Zygmuntowicz, who has been the subject of the book "The Violin Maker," is the focus of Dustin Cohen's first episode of his "Made In Brooklyn" series. Watch him discuss how professional musicians are like the world's top athletes in the video below.
