The magic bullet is a scientific concept developed by a German Nobel laureate Paul Ehrlich in 1907.[1] While working at the Institute of Experimental Therapy (Institut für experimentelle Therapie), Ehrlich formed an idea that it could be possible to kill specific microbes (such as bacteria), which cause diseases in the body, without harming the body itself. He named the hypothetical agent as Zauberkugel,[2] and used the English translation "magic bullet" in The Harben Lectures at London.[3]
