favorite sort of music: early choral composition by Tallis and Purcell. He was not churchgoing, but it was liturgical music that moved him the most, and he sat very still and upright in the old wooden pew for the duration of every song, his head bowed as if in prayer. Only his fingers moved from time to time, playing his knees like an organ.
Afterward David would walk swiftly out the door, and Ada would run to keep pace with himâdifficult to do, for he walked as if he wereskating, with a lengthy, forceful strideâand turn left toward Gramercy Park, and then stand silently with Ada outside of the house for several seconds. They never spoke. Usually the heavy drapes inside the house were drawn by the time the concert let out, but once Ada saw a young girl, about her age, sitting with her mother at a dining room table. âI wonder if those are Ellises,â said David idly, naming the family who purchased the home after the death of his parents. âI read about them in the paper. Iâve never met them.
âI would have been the only heir,â he told Ada. âI wouldnât have taken it anyway,â he added, and then he walked quickly down the street, without warning her, so that she had to run for several steps to catch him.
Despite his complete dismissal of his past, he kept one black-and-white portrait of himself with his parents in the dresser in his bedroom. Ada had discovered it when she was quite young and often returned to it whenever he was out. There he was, young David, perhaps eleven years old. In the picture he was wearing a bow tie, a tweed jacket with a high waist, short pants, knee socks. A very slight smile played upon his mouthâsame mouth, same lively light eyes. His parents looked predictably dour and serious: mother in a black scoop-necked satin dress that ended just above her ankles, black stockings and black shoes, a long black beaded necklace. Father in a dark suit and tie, one leg crossed over the other. All three of them were positioned slightly apart from one another. In the background was a funny scene: draperies, slightly askew, framed a fuzzy, impressionist backdrop of trees and mountains.
Their next-door neighbor on Shawmut Way was an old woman named Mrs. OâKeeffe, who had come over from Ireland at ten years old, in 1910. She had worked as a maid in the same neighborhood David had grown up in, and then she met her husband and moved to Boston. This coincidence came up early in their acquaintance, and Ada watched David as he physically cringed. Discussions about his past were always an encumbrance to him, but from then on he haddifficulty dodging Mrs. OâKeeffe, who wished frequently to reminisce with him about the other families who had occupied those homes. She had not known him but she had known his people. She would name the families of Gramercy Park as if counting her treasures. âAnd the Cromwells,â she would say, âwhat a beauty their daughter was. And those Byrons, and those Harts, and those Carringtons . . .â
âYes,â David would say, âI knew all of them, once.â
He graduated high school in 1943, right in the middle of the Second World War, which normally would have guaranteed a period of service. But David was, even at that age, nearsighted to the point of legal blindness without his glasses. Instead, therefore, he went to college. He chose Caltechâwhich further horrified his father, who had gone to Harvard, and his mother, who saw it as a vocational school, a school for the working class. There he majored in mathematics. He then found his way to the Bit, where he received a doctorate in applied mathematics, and where his work on GOPAC, an early computer system spearheaded by Maurice Steiner, earned him such quick fame in his field that he was given his own lab at the Bit by President Pearse at the age of thirty. It was named for Steiner, after his death, and with David at the helm, it quickly became
