Born in London in 1950, the son of two scientists: Masado Banzai, a brilliant Japanese research physicist whose work in theoretical quantum mechanics is reported to have "rattled" Albert Einstein, and Sandra Willoughby, the daughter of the eccentric Scottish-born Texas mathematician Edward McKay Willoughby.
In 1946 Masado Banzai and Sandra Willoughby joined forces with Masado's old friend and colleague, Professor Toichi Hikita, who shared their belief that one day man would be able to pass unharmed through solid matter.
