Ever notice how many of the great jazz organists came from Pennsylvania? Jimmy Smith, Jimmy McGriff, and from an earlier era, Bill Doggett, all hailed from the Philadelphia area. And from Pittsburgh came Gene Ludwig, who was the last major jazz organist from the 1960s still active when he died in 2010.
Ludwig switched to organ from piano after seeing Smith perform at a Pittsburgh club. Although he never achieved the level of popularity of Smith and McGriff, Ludwig performed steadily for nearly 50 years.
