John von Neumann introduces the concept of a stored program in the first draft of a report on the Electronic Discrete Variable Automatic Computer (EDVAC) is published. Brian RanDell notes, “It is generally accepted that the first documented discussion … of the advantages of using just one large internal memory, in which instructions as well as data could be held, was the draft report on EDVAC written by Von Neumann.” The draft report contains a description of the planned machine and the reasoning behind the various design decisions.

The first US atomic bomb (named “Able) is dropped as a part of Operation Crossroads.

The point-contact transistor is first publicly demonstrated by its inventors, John Bardeen and Walter Brattain, scientists at the Bell Telephone Laboratory in Murray Hill, New Jersey.

As it is developed over the next few years, it will become the successor to the vacuum tube.
