In August 1925, 14 Camp Chesterfield mediums were arrested on charges of obtaining money under false pretences. The charges were filed by a news service reporter who had spent time investigating the camp. In 1960, psychic investigatorAndrija Puharich and Tom O'Neill, publisher of the Spiritualist magazine Psychic Observer, arranged to film two seances at Camp Chesterfield using infrared film, intending to procure scientific proof of spirit materializations. The medium was shown the camera beforehand, and was aware that she was being filmed. However, the film revealed obvious fraud on the part of the medium and her cabinet assistant. The expose was published in the 10 July 1960 issue of the Psychic Observer. Well-known writer on paranormal topics Allen Spraggett visited the camp in 1965, and was unconvinced by the spirit materializations during seances: In 1976, M. Lamar Keene, a former medium in Florida and at Camp Chesterfield, confessed to defrauding the public in his book The Psychic Mafia "as told to" Allen Spragett. The book was also provided with a foreword by the writer William V. Rauscher. In the text Spragett and Keene detailed a multitude of common techniques utilized by fraudulent mediums since the 19th century to conjure spirits. Spragett and Keene wrote that beneath the church is a storehouse of personal data about Camp Chesterfield visitors which is collected during church service when parishioners are asked to provide their full name, the names of loved ones they wish to contact, and questions. A medium is blindfolded and claims to read the data through the help of spirit guides. The pieces of paper are not returned to the parishioners; rather, Spragett and Keene wrote, the data is shared freely amongst Camp Chesterfield mediums as well as those networked across the country for use in private hot readings. A regular contributor to Fate magazine wrote about a grieving couple who had recently lost their child, and went to Camp Chesterfield hoping to contact their child. However, when they were requested to write down the names of those they wished to contact, they wrote down, along with their child, the names of two fictitious relatives. Later in seances those two nonexistent relatives materialized and spoke to them. In March 2002, The Skeptical Inquirer published a sting operation performed by former magician and prominent skeptical paranormal investigator, Joe Nickell. Nickell exposed further fraud on the part of mediums at Camp Chesterfield.
Historic district
Camp Chesterfield was added to the National Register of Historic places because of its significance as a Spiritualist Camp of a type that was widespread in the eastern and Midwestern United States at the start of the 19th century. As was typical for the design of these camps, is contain a common public space at its center surrounded by closely spaced residences. Simple tents and wooden summer cabins were used at Camp Chesterfield's start in 1890. Shared facilities such as a dining hall, lodging house, tent auditorium, and two seance cabins were also present. None of these structures still exist. As the movement gained in significance at the turn of the century, permanent buildings were added including a church, meeting house, and homes. Several of these buildings still exist, including a 1914 two-story hotel. The last major development phase of the camp occurred after World War II, including a 1949 hotel, 1954 cathedral, and a 1958 art gallery. The historic site consists of 40 contributing buildings, 9 structures, and 2 objects. The structures include several stone bridges and a stone sweathouse, the objects are a Native American memorial and a totem pole.
