What these qualities meant, how they conjoined to form a human being who looked and moved a certain way, I had no idea. As a teenager, I first became aware of people’s eyes catching on me as I walked down Michigan Avenue with my mother and Grace during shopping trips to Chicago. They glanced, then looked—each time, I felt a prick of sensation within me. I knew how transistors worked; my father had shown me a picture of the very first one, at Bell Labs, a crusty, inauspicious-looking rock that had performed the revolutionary feat of transmitting and amplifying electrical current. The jabs of interest I provoked in strangers struck me as an unharnessed energy source; somehow, I would convert them into power.
