Ben Selvin
Benjamin Bernard Selvin (March 5, 1898 – July 15, 1980) was an American musician, bandleader, and record producer. He was known as the Dean of Recorded Music. According to The Guinness Book of World Records, Selvin recorded more musical sides (on 78-rpm discs) than any other person. One reason for this prolific output is that he recorded for dozens of different record labels during this productive time in the industry, using a different name for each label. His output has been estimated at 13,000 to 20,000 song titles.
