Today we are going through walk-through metal detectors to enter courtrooms, airports, and even in concert halls. But back in the 1920’s the first walk-through metal detectors were not invented to find weapons. They were invented to detect stolen metal objects. The first walk-through metal detectors date back to the 19th century, but in the 1920s, two scientists in Germany devised a way to detect stolen machine objects in factory workers without having to exercise physical control in each working one by one.

In the mid-1920s, H. Geffchen and H. Richter of Leipzig devised the walk-through metal detector – their “radio detective” – for a large manufacturing plant in Germany. Without any physical contact, their invention “made an effective search for every person leaving the premises” and decided “with certainty and instantness if he brings with him any object of a metal character”. There is no longer annoying body control and a waste of time that leaves room for errors.
