Gordon Moore , the electronics pioneer who co-founded Intel Corp. and whose groundbreaking theories defined the tempo of innovation in semiconductors, has died at the age of 94. A 1965 article by Mr. Moore published in the trade journal Electronics predicted the pace of miniaturization in computer chips and anticipated the development of home computers, smart wristwatches, automatic controls for cars and other inventions as electronic components etched on squares of silicon become smaller, faster and cheaper. Moore’s Law, as his prediction became known, proved a remarkably accurate observation about how quickly engineers would create advances in digital technology that have led to countless fixtures of modern life.
