In the summer of 1916, John Henry Deichman drafted what would become the most copied acoustic guitar design to this day. While later foreman, Deichman also patterned the first "OM's" for Martin, helping transform the nearly 100 year-old company into the leading manufacturer of steel-string flattop guitars. With the help of his family, "Birth of the Dreadnought" devotes an entire chapter to John and the genius that was, Deichman.
