Problem: Stephen Arthur Stills (born January 3, 1945) is an American singer, songwriter, and multi-instrumentalist best known for his work with Buffalo Springfield and Crosby, Stills, Nash & Young. Beginning his professional career with Buffalo Springfield, he composed one of their few hits "For What It's Worth," which became one of the most recognizable songs of the 1960s. Other notable songs he contributed to the band were "Sit Down, I Think I Love You

Stills was involved with the musician Judy Collins from 1968 to 1969 and wrote the song "Suite: Judy Blue Eyes" for her. He dated actress and singer-songwriter Nancy Priddy who was the inspiration for his Buffalo Springfield song "Pretty Girl Why". He also had a short-term relationship with Rita Coolidge, as had Graham Nash, which apparently led to the initial breakup of CSN, in 1970. During a Manassas tour in France, Stills met and married his first wife, the singer-songwriter Veronique Sanson. Their son Christopher was born in 1974. They divorced in 1979. In 1976, Stills told Rolling Stone, "My hearing has gotten to be a terrible problem. If I keep playing and touring the way I have been, I'll go deaf." In 1988, he married the Thai model Pamela Anne Jordan, with whom he had a daughter, Eleanor. His third wife is Kristen Hathaway (Kristen Stills), whom he married in 1996.  Stills's son, Justin Stills, was born in 1972 to Harriet Tunis. Justin was critically injured while snowboarding on Mt. Charleston, just outside Las Vegas, in 1997. An episode of Discovery Health's documentary series Trauma: Life in the ER featured his treatment and recovery. Another son, Henry, has been diagnosed with Asperger syndrome  and is profiled in the 2007 documentary Autism: The Musical. Stills's daughter Eleanor is a photographer and graduate of Art Center College of Design in Pasadena. Since Eleanor's graduation, she has been responsible for all recent Crosby, Stills & Nash photography. Stills has another daughter, Alex, who attends Emerson College in Boston, Massachusetts. His son Chris and daughter Jennifer are both recording artists. His youngest son, Oliver Ragland, was born in 2004 and named in honor of Neil Young, whose maternal family name is Ragland.  Like all four members of CSNY, Stills has long been involved in liberal causes and politics. In 2000, he served as a member of the Democratic credentials committee from Florida during the Democratic National Convention, and was a delegate in previous years.  The comic book series Scott Pilgrim features a character by the name of Stephen Stills, referred to as "the Talent" by the band he shares with the title character. The character also plays an acoustic guitar and sings, and is often portrayed wearing the kind of western shirts that is part of Stills's standard wardrobe. The series also has a reference to Stills's collaborator Neil Young in the character of Young Neil.

Question:
Although Price claimed his birth was in Shropshire he was actually born in London in Red Lion Square on the site of the South Place Ethical Society's Conway Hall. He was educated in New Cross, first at Waller Road Infants School and then Haberdashers' Aske's Hatcham Boys School. At 15, Price founded the Carlton Dramatic Society and wrote plays, including a drama, about his early experience with a poltergeist which he said took place at a haunted manor house in Shropshire. According to Richard Morris, in his recent biography Harry Price:
On 7 October 1930 it was claimed by spiritualists that Eileen J. Garrett made contact with the spirit of Herbert Carmichael Irwin at a seance held with Price at the National Laboratory of Psychical Research two days after the R101 disaster, while attempting to contact the then recently deceased Arthur Conan Doyle, and discussed possible causes of the accident. The event "attracted worldwide attention", thanks to the presence of a reporter. Major Oliver Villiers, a friend of Brancker, Scott, Irwin, Colmore and others aboard the airship, participated in further seances with Garrett, at which he claimed to have contacted both Irwin and other victims. Price did not come to any definite conclusion about Garrett and the seances:  It is not my intention to discuss if the medium were really controlled by the discarnate entity of Irwin, or whether the utterances emanated from her subconscious mind or those of the sitters. "Spirit" or "trance personality" would be equally interesting explanations - and equally remarkable. There is no real evidence for either hypothesis. But it is not my intention to discuss hypotheses, but rather to put on record the detailed account of a remarkably interesting and thought-provoking experiment.  Garrett's claims have since been questioned. The magician John Booth analysed the mediumship of Garrett and the paranormal claims of R101 and considered her to be a fraud. According to Booth Garrett's notes and writings show she followed the building of the R101 and she may have been given aircraft blueprints by a technician from the airdrome. However, the researcher Melvin Harris who studied the case wrote no secret accomplice was needed as the information described in Garrett's seances were "either commonplace, easily absorbed bits and pieces, or plain gobbledegook. The so-called secret information just doesn't exist."
