A bachelor schoolteacher for a long time, since the combination of poverty and living with a difficult, needy mother had made it difficult for him to attract steady girlfriends. But his mother had passed away in the mid-1970s and he had struck up a relationship with a much younger woman—one of his former students, whom he had encountered by chance on the subway, years after her graduation. They had gotten married in 1979. Bartos had been born in 1982 and Csongor in 1985. Father was a lovely man, but already in his midforties. Smoking several packs a day, he had burned his body out like a meat cigarette and died when Csongor was ten years old. Though not before he had succeeded in downloading most of what he knew of mathematics into the mind of Bartos and, to a lesser extent, Csongor.
