Ghost

'''Kuttner, Henry. "Ghost."' Astounding'' May 1943.

Discussed by John Foyster, "The Long View 4," ASFR 2nd series #9, 2.4 (July 1987): 13-14: the premise is "that computers may be susceptible to human neuroses," combined with "a case for the existence of 'real' ghosts by technological rather than supernatural means" in that a man's "'ghost' . . . haunts the research station by the manifestation of his personality through the infected computers."
