An English mill-owner's son, Pitman ran a school where he used music to teach mathematics and improved a form of Taylor's shorthand system. The publisher Bagster pushed for further improvements, resulting in Pitman's Stenographic Sound-Hand (1837). More than twenty editions and a name change (Phonography) witness its influence. There was a phonetic printing version (phonotypy), though its purpose is unclear. His grandson, (Isaac) James Pitman (1901–85), was also a publisher.
