David H. Hubel was born in Windsor, Ontario, Canada, to American parents in 1926. His grandfather emigrated as a child to the United States from the Bavarian town of Nördlingen. In 1929, his family moved to Montreal, where he spent his formative years. His father was a chemical Engineer and Hubel developed a keen interest in science right from childhood, making many experiments in chemistry and electronics. From age six to eighteen, he attended Strathcona Academy in Outremont, Quebec about which he said, "[I owe] much to the excellent teachers there, especially to Julia Bradshaw, a dedicated, vivacious history Teacher with a memorable Irish temper, who awakened me to the possibility of learning how to write readable English." He studied mathematics and physics at McGill University, and then entered medical school there.
