In St. Paul's Cathedral there stands a monument representing a man with a key in his right hand and a scroll in his left, whilst on the pedestal from which he looks down are pictured relics of the prison life of the past. The man is John Howard, who travelled tens of thousands of miles, and spent many years in visiting gaols all over England and the Continent, and in endeavouring to render prison life less degrading and brutalising. Wherever he went prison doors were unlocked as if he possessed a magic key; and by his life and books he did more to help prisoners than any other man.
