Some of Hubbard's later works included acknowledgements to both Thompson and White, and Hubbard would later claim to have received clinical training from Thompson and White. In contrast, Hubbard spoke more critically of his later encounters with psychiatrists and psychiatric institutions—Hubbard had written positively of psychiatric hospital superintendent William Alanson White, but White's successor (Winfred Overholser) was singled out for criticism. Hubbard likewise spoke critically of his encounters with a Washington, D.C. institution for the treatment of schizophrenia called "Walnut Lodge" (presumably Chestnut Lodge). During the Second World War, Hubbard was hospitalized at Oak Knoll Military Hospital. In 1947, Hubbard wrote a letter to the VA requesting psychiatric treatment. The following year, Hubbard and his wife Sara moved to Savannah, Georgia, where Hubbard would later recall having been associated with a charity mental health clinic. According to Hubbard, he worked as a volunteer helping to treat charity patients during his time in Savannah. While in Savannah, Hubbard began working on a "book of psychology" about "the cause and cure of nervous tension"; the next year, he published Dianetics: The Modern Science of Mental Health. In 1951, Hubbard's wife Sara reportedly consulted a psychiatrist who recommended Hubbard be institutionalized. Hubbard initially responded by kidnapping Sara. Thereafter, he took their daughter and fled to Havana. After Sara went public with her story, Hubbard returned her daughter. In his final known encounter with a psychiatrist, Hubbard consulted a practitioner in order to rebut public claims of his own mental illness. Thereafter, Hubbard was increasingly hostile towards psychiatry. In the 50s, Hubbard sought to identify "Subversive" psychiatrists or other "Potential Subversives". By the early 70s, Hubbard wrote of having redefined the word "psychiatrist" to mean "an antisocial enemy of the people". Hubbard's early encounters with psychiatry Hubbard claimed to have personal encounters with several named psychiatrists beginning in his childhood. Some, like Thompson and White, would later be remembered favorably—Hubbard explicitly cited both as sources for his work. Others, such as Overholser and Center, were the subject of scorn. Joseph Cheesman Thompson In 1923, Navy medical doctor and psychoanalyst Joseph "Snake" Thompson accompanied Hubbard on a voyage. Hubbard recalled "I traveled with Commander Thompson from Seattle, Washington through the Panama Canal to Washington, D.C. when I was about twelve and knew him during all that time that I was in Washington and later." Hubbard recalled that "[Thompson's] friends called him 'Snake' and his enemies
