Ask Robert Dennard about the invention of DRAM, and he will probably do three things.

First, he will show you the patent notebooks IBM encouraged its inventors to keep, which hold all his ideas about dynamic random-access memory, meticulously dated and witnessed by other people, “to make sure we had proof of our inventions." He stores these pristine notebooks in an armoire under a wall crowded with his awards.

The Device That Changed Everything

Transistors are civilization’s invisible infrastructure

This replica of the original point-contact transistor is on display outside IEEE Spectrum’s conference rooms.

Randi Klett

I was roaming around the IEEE Spectrum office a couple of months ago, looking at the display cases the IEEE History Center has installed in the corridor that runs along the conference rooms at 3 Park. They feature photos of illustrious engineers, plaques for IEEE milestones, and a handful of vintage electronics and memorabilia including an original Sony Walkman, an Edison Mazda lightbulb, and an RCA Radiotron vacuum tube. And, to my utter surprise and delight, a replica of the first point-contact transistor invented by John Bardeen, Walter Brittain, and William Shockley 75 years ago this month.

I dashed over to our photography director, Randi Klett, and startled her with my excitement, which, when she saw my discovery, she understood: We needed a picture of that replica, which she expertly shot and now accompanies this column.
