Perry L. Harrington

There is no known author named 'Perry L. Harrington'; the name appears to be a confusion with Perry Donell Harrington, an American former professional football player (running back) who played for the Philadelphia Eagles and St. Louis Cardinals from 1980–1985[1]. Perry Donell Harrington was born March 13, 1958, and after retiring from the NFL worked in banking and railroad marketing before retiring[1][2].
