Who invented stored-program concept?

John von Neumann had proposed the stored-program concept In the late 1940's, that a program could be electronically stored in binary format in computer memory and the instructions could be modified by the computer as determined by the calculated results and a stored program in the computer memory enables it to perform a variety of tasks in a prefixed order or discretely.

John was born to affluent Jewish parents. He is known as an applied mathematician, a physicist, an inventor, a computer scientist, and a polymath. He made major contributions to versatile fields like mathematics, physics, economics, computing, and statistics.
