Good rediscovered irrational numbers and the infinity of solutions of 2×2 = y2+1 at the age of 9. He rediscovered mathematical induction and, in a sense, integration, at the age of 13. In 1943, Good was one of seven people who helped design Mark II of a large-scale (classified) binary electronic digital computer called Colossus (which was not entirely general purpose).
