THE INSTITUTEIt has been 10 years since IEEE set aside a day to commemorate the anniversary of the meeting in Philadelphia in 1884 when members of the American Institute of Electrical Engineers, one of IEEE’s two predecessor societies, gathered for the first time to share technical ideas.

Since then, IEEE Day has grown in popularity. For some sections, one day is not enough, so celebrations now are held throughout the first two weeks of October to accommodate those that prefer to hold weekend events.

Even as the initial sales receipts for the first transistors to hit the market were being tallied up in 1948, the next generation of transistors had already been invented (see “The First Transistor and How it Worked.”) Since then, engineers have reinvented the transistor over and over again, raiding condensed-matter physics for anything that might offer even the possibility of turning a small signal into a larger one.
