John Augustus (c. 1785 – June 21, 1859) was an American boot maker and penal reformer.
He is credited with coining the English term "probation"[1] and is called the "Father of Probation" in the United States because of his pioneering efforts to campaign for more lenient sentences for convicted criminals based on their backgrounds.
His interest in prisoner rehabilitation began in 1841, when he was touched by the case of a man arrested for public intoxication and paid his bail, moving the judge to set the man free.
His work brought him the devotion and aid of many Boston philanthropists and organizations.
At his death, it was noted that of the 1,946 people he helped, only ten proved unworthy (for which he forfeited bail).
