Taipei
David was born in a small apartment in the Da'an district of Taipei, in the spring of 1955, six years after his parents had come to Taiwan from Shanghai. His father Kwong was a civil engineer, trained at Jiao Tong in the years before the war. His mother Mei had a mathematics degree from Yenching University in Beijing and had taught briefly at a girls' school before leaving for Taipei with her husband.
David was the older of two. His sister Alice came in 1958. The apartment had two rooms, a small balcony, and a view of a public park. His father worked long hours on the reconstruction of southern Taiwan's roads. His mother taught him mathematics at the kitchen table from the age of four.
He drew constantly. His mother saved everything — three ring binders full, before he was ten, of small careful pencil drawings of buildings, bridges, streetcars, and, once, an entire imagined city on the back of six pieces of taped-together brown paper. His father, who did not know quite what to do with a boy who preferred pencils to arithmetic, kept his own counsel and quietly bought David a drafting board for his tenth birthday.
