Peter Aykroyd spent his childhood watching his family's parlor seances through the crack of a basement door. Here, for the first time, Aykroyd tells the strange and delightful story that inspired his son, Dan, to make the mega-hit Ghostbusters.

Part history, part family legend, A History of Ghosts starts in 1848 in upstate New York, where the spiritualist craze first began. Aykroyd introduces the listener to notable mediums while telling the story of the development of spiritualism, interweaving a personal history marked by a fascination with ghosts and spirits with the larger narrative about the role the paranormal has played in our culture. Such legendary figures as Sir Arthur Conan Doyle and Harry Houdini appear - and vanish.

Everyone loves a good ghost story. Successful TV shows such as Medium and Ghost Hunters are proof that our national obsession with ghosts is here to stay. Millions of Americans believe in the paranormal'and even skeptics have heard a bump in the night and suspected it might be something supernatural.
