CPR has come a long way since it was first introduced. Early methods of resuscitation began in the 1500s, ranging from whipping the unconscious person to rolling them repeatedly over a barrel. Throughout, doctors and scientific organizations discovered the methods used in the CPR process today. The Paris Academy of Sciences first recommended mouth-to-mouth resuscitation in 1740. Dr. Friedrich Maass performed the first documented instances of chest compression in 1891. Modern CPR techniques were first introduced in 1950
