"

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.[8] 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.[9] According to Hubbard, he worked as a "lay analyst" or volunteer peer counselor, listening to charity patients during his time in Savannah.[citation needed] 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.[10]
