Aka DtD soulwinning. This is purely a historical question. The purpose of this thread is not the discussion of the propriety of the practice. When did the current practice of Door to Door "Visitation/Sulwinning" develop? I don't think that it existed in its current form until after WWII. But, that is an unsubstantiated gut feeling. Anybody with a firmer grasp of the modern history of this practice?
