Maurice Grosse (6 March 1919 – 14 October 2006) was a British paranormal investigator famous for his involvement in the Enfield Poltergeist case from 1977-1979, he has subsequently been portrayed in The Enfield Haunting (2015) by Timothy Spall and most recently in The Conjuring 2 (2016) by Simon McBurney.
Grosse was educated at the Regent Street Polytechnic in London. After serving an apprenticeship in commercial art and design, he served in the Second World War with the Royal Artillery and was among those evacuated from Dunkirk in June 1940. Commissioned in 1941, he became responsible for the guarding and welfare of Italian prisoners of war for the remainder of the war. He married his wife Betty Grosse in 1944 and they had two daughters and a son. After the war he became an inventor, and he filed the first of his many mechanical patents in 1945. His most successful invention was the rotating advertising billboard. In 1961 Grosse founded his own design and engineering consultancy business which became responsible for launching many patents throughout the world.
A personal tragedy launched Grosse into psychical research, when his daughter Janet was killed in a motorbike accident in August 1976. Following her death, Grosse reported that members of his family experienced a number of coincidences and psychic happenings, and this led him to join the Society for Psychical Research and the Ghost Club. In September 1977 he investigated an alleged poltergeist in a house in Green Street, Enfield, North London, that later became known as the Enfield Poltergeist. Grosse claimed to have recorded many hours of audio and video evidence of the poltergeist while staying at the house for long periods of time, along with another psychical investigator Guy Lyon Playfair who later wrote the book, This House is Haunted (1980).
