I had seen this woman before. Many times now. I was certain of it. But who was she? In a film from 1947, she’s operating an electric Chinese typewriter, the first of its kind, manufactured by IBM. Semi-circled by journalists, and a nervous-looking middle-aged Chinese man—Kao Chung-chin, the engineer who invented the machine—she radiates a smile as she pulls a sheet of paper from the device. Kao is biting his lip, his eyes darting back and forth intently between the crowd and the typist.
