This gifted musician was part of the duo Mac & Bob, which featured two blind musicians who met while studying music at the Kentucky School for the Blind. They teamed up in the early '20s and soon attracted record company scouts. During their active career they recorded at least 200 songs with sales reported to be more than one million copies. The duo apparently taught each other songs by punching out representations of musical notes and song lyrics that approximated a crude variation on the braille system. ~ Eugene Chadbourne
