Simon Phillips Norton (born 1952) is a mathematician in Cambridge, England, who works on finite simple groups. He constructed the HaradaNorton group, and in 1979 together with John Conway proved there is a connection between the Monster group and the jfunction in number theory. They dubbed this monstrous moonshine and made some conjectures, later proved by Richard Borcherds. He also made several early discoveries in Conway's Game of Life.^{[1]}
