Historical Basis

Ferdinand Waldo Demara

Ferdinand Waldo Demara Jr. was born on December 21, 1921, in Lawrence, Massachusetts, to a middle-class family that suffered financial hardship during the Great Depression. He dropped out of high school at age 16 and ran away from home in 1937, initially attempting to join the Trappist order of monks at a Cistercian monastery in Rhode Island, but was dismissed two years later due to his unsuitable temperament. In 1941, during World War II, he enlisted in the U.S. Army under a false name but deserted after 15 months; he then joined the U.S. Navy, where he was accepted for medical training but faked his death and fled upon discovery. He was arrested in 1945 for desertion and served 18 months in prison, released in 1946 for good behavior. His early impersonations began in the 1940s, including posing as Dr. Robert Linton French, a teacher of psychology and English at a junior college in Pennsylvania from 1942 to 1945, and later as a sheriff's deputy in Washington state, where he was arrested for fraud. Demara's charisma and self-taught skills, including a claimed photographic memory, enabled these deceptions, driven by a deep-seated desire for respect, adventure, and prestige rather than financial gain. Among his notable impersonations, Demara posed as an assistant prison warden named Ben W. Jones at Huntsville Prison in Texas in 1955, implementing reforms before fleeing upon recognition. He also assumed monastic identities, joining the Brothers of Christian Instruction in Maine in the early 1950s after multiple failed attempts with other Catholic orders, and briefly worked as Dr. Cecil Hamann, a biologist and teacher, at a Boston hospital. His most daring exploit occurred during the Korean War, when he enlisted in the Royal Canadian Navy in March 1951 as Surgeon-Lieutenant Dr. Joseph Cyr, despite lacking any medical training. Aboard the destroyer HMCS Cayuga, Demara performed 16 successful surgeries on wounded sailors, relying on medical textbooks and his quick learning; all patients survived, earning him praise from the crew before his identity was exposed by the real Cyr's family via a news report. The Navy discharged him honorably that year with back pay but deported him to the United States. He faced further legal troubles, including a 1957 arrest in , for teaching without credentials, resulting in probation. In 1951, while posing as Brother John, he co-founded LaMennais College in Alfred, Maine, under the Brothers of Christian Instruction; the institution relocated and evolved into part of in after his departure. In his later years, Demara pursued legitimate paths, earning a degree from a in in 1967 and working as an ordained Baptist minister and counselor at Good Samaritan Hospital in , from 1967 until health issues forced his retirement around 1980. He appeared on television, including an episode of in 1959, where he openly discussed his past as "the Great Impostor." Demara died of a heart attack on June 7, 1982, at West Anaheim Community Hospital, at age 60. Psychologically, his actions stemmed from a need for validation and excitement, often rationalized as benevolent intentions, though he grappled with guilt, , and fear of exposure throughout his life. These real-life events inspired the 1961 The Great Impostor, which fictionalized his story for dramatic effect.

Robert Crichton's Book

Robert Crichton, a and author, published The Great Impostor in 1959 through , following extensive interviews and time spent with Jr. at a where Demara was then living.

Inspired by a sense of and , Bert briefly enlists in the U.S. Navy but deserts shortly after, marking the start of his pattern of evasion and reinvention. He then forges credentials to join the U.S. Army as a supply officer, only to impersonate a Marine sergeant named Robert Lloyd Gilbert, a supposed Yale graduate, where his charisma helps him rise quickly before the FBI closes in, prompting him to stage a fake and flee. Seeking refuge, hides out in a monastery in , adopting the role of Brother John, where he excels in scholarly pursuits but chafes under the strict monastic discipline, eventually getting expelled for his independent spirit.
