The year 1913 marked the beginning of an extraordinary relationship between an impoverished Indian clerk and a Cambridge don. A century later, their remarkable friendship has left its mark in the strangest of places, namely in Futurama, the animated series from The Simpsons creator Matt Groening and physics graduate David X Cohen.
GH Hardy (1877-1947) and Srinivasa Ramanujan (1887-1920) were the archetypal odd couple. Hardy, whose parents were both teachers, grew up in a middle-class home in Surrey, England. At the age of two he was writing numbers that reached into the millions, so it was no surprise that he eventually read mathematics at Trinity College, Cambridge, where he joined an elite secret society known as the Cambridge Apostles.
