Dr. Erroll completed U.S. military service in Germany, studied psychology at the
College of the City of New York, earned his degree in psychology from the University of Helsinki and his Ph.D. at the Derner Institute, Adelphi University.

As a clinical psychologist, Dr. Erroll worked at the Suffolk County Correctional
Facility in Riverhead, and while there developed the Y.E.S.program with Ray Jacquin, deputy warden, bringing H.S. students into the prison for the purpose of exposing them to the realities of bad judgment.

During retirement, Dr. Erroll was curator of NYCʼs General Society of Mechanics & Tradesmenʼs Mossman Collection of bank vault locks and time locks. He developed an extensive knowledge and collection of time locks and, with his son, David, produced American Genius, a definitive history and photographic record of early American bank vault locking technology.
