Robert John Christo, popularly known as Bob Christo, was born in 1938 in Sydney, Australia. After completing his civil engineering in Sydney, he took on projects which involved supporting the military supply lines of the South Vietnamese army and working as construction supervisor on the film sets of Apocalypse Now. Led by his instincts, Christo zealously followed one aspiration after another: chasing after a lost spy ship, running an escort service, modelling for African beer, singing in rock concerts, and so on.
