Peter Underwood was born in 1923 at Westholm Green, Letchworth.
He became interested in ghosts from an early age, and started to visit reportedly haunted places. He followed reports in the press, and quickly began to invest serious time and energy into investigating the paranormal, which became his life’s work.
He believed there was a natural explanation for almost all reports of ghosts, however a small percentage of genuinely inexplicable cases held open the possibility that in future it may yet be possible for evidence to be found - that could hold up to scientific scrutiny - for the existence of ghosts.
