In January 1958, Will Burtin unveiled an object at the annual convention of the American Medical Association that few people in the room could quite categorise. It was a walk-through model of a basic animal cell — twenty-four feet across, twelve feet high, built from clear plastic and aluminium, with about a mile of electrical wiring running through it to animate the organelles with pulsing light. The scale was one million to one. You entered through the cell membrane. You stood beside the nucleus.
Nothing like it had been built before, in any material. The Cell reached an estimated forty million people through its tour and subsequent coverage in Newsweek and Life. Burtin was fifty years old. He had been working toward this kind of problem — how do you make invisible biological processes graspable? — for the better part of a decade.
