Exorcism Exposé

Take an in-depth look at Saint Louis University's part in the most famous exorcism of the 20th century.

The spirit of the story is always the same, but the specifics are all over the place.

You know The Exorcist? It happened at Saint Louis University.

It happened in DuBourg Hall. On the fourth floor, in a room that has been sealed off for years.

A light is kept on in the room, still. The door is only unlocked to change the light bulb. There's a bloody handprint on one of the walls. A giant cage.

No, it wasn't in DuBourg. It was Verhaegen Hall. It was the College Church basement. Jesuit Hall.

In hushed tones, upperclassmen tell the story to freshmen during their first days on campus, or maybe once the air turns cold in the fall. New employees hear about it, too, especially if they end up in one of the infamous locations.

A University legend at this point, the story includes its share of error, exaggeration and fabrication. Here is the real story.

Possession Obsession

"Without a doubt, the topic I'm asked about most frequently is the exor­cism," said John Waide. "I get more requests around Halloween, but it's a popular question year-round."

Waide (A&S '73) has worked at Pius XII Memorial Library for 40 years and was the University archivist for more than two decades. He knows SLU history forwards and backwards. So it's a little unsettling when he begins the story of the 1949 exorcism by acknowledging, "There are dozens of versions of what happened."

Don't even think about consulting William Peter Blatty's 1971 book The Exorcist or the 1973 film it became. The version Waide puts the most stock in is Thomas B. Allen's Possessed: The True Story of an Exorcism, a historical account based on two primary sources: a detailed diary kept by Raymond Bishop, S.J., who assisted during the rite, and lengthy interviews with Walter Halloran, S.J., another assistant who was one of the last living eyewitnesses to the exorcism.

On a gray, stormy afternoon last fall, Allen visited Saint Louis University to headline "The St. Louis Exorcism of 1949" discussion hosted by University libraries special collections and the office of mission and ministry. Waide, John Padberg, S.J., a Jesuit historian and scholar, and Paul Stark, S.J., vice pres­ident for mission and ministry, rounded out the panel and provided historical and ecclesial context for the events of early 1949. A crowd of more than 700 spilled into the stacks at Pius Library, and the panel members held them in thrall as they recounted the story.

Tell the Truth and Shame the Devil

A self-proclaimed "Jebbie boy" with six years of Jesuit education in his past, Allen was a freelance writer in the early 1990s when he came across a brief note in a Washington Post gossip column about Halloran giving an interview about the exorcism to a Nebraska newspaper. Intrigued - and thinking he'd pen something about it for the Washingtonian - Allen started tracking down the Jesuit. He contacted him on Halloween, of all days, and the two ended up becoming friends. 

"He was what the Irish call 'a solid man,'" Allen said. "And he never was certain about whether or not the boy was possessed."

As Allen tells it, Halloran's involvement in the exorcism came about almost by chance. 

In 1949, Halloran was a Jesuit scholastic studying history at Saint Louis University. He also happened to be a driver for William Bowdern, S.J., then the pastor of St. Francis Xavier College Church. One night, Bowdern asked Halloran to drive him and another Jesuit to dinner at a home in a northwest St. Louis suburb. Halloran had no idea what he was getting into.

"He thought he'd be waiting outside, but when they pulled up to the house, Bowdern turned to him and said calmly, 'I'll be doing an exorcism. I want you to hold the boy down in case it's needed,'" Allen said.

What happened that night - and for weeks afterward

- is still somewhat shrouded in secrecy.

What the Devil Really Happened?

The story began a couple months before Halloran showed up on the scene. 

In January 1949, a 13-year-old Maryland boy -- not the 12-year-old girl depicted in The Exorcist -- started experiencing strange, troublesome episodes: scratching sounds coming from the walls and floor of his room, the sound of water dripping, move­ment of a mattress and other objects. At first, his family thought he might have been plagued by the spirit of a recently deceased aunt, who had introduced the boy to the Ouija board. The family con­sulted physicians, psychiatrists and a minister from their Lutheran church. They grew desperate as the situation worsened.

"They go to Rev. Luther Miles Schulze, a Lutheran minister who happened to be greatly interested in the paranormal, as it was called at that time, and he said, 'Go to a Catholic priest; the Catholics know about this kind of thing,'" Allen said.

(Incidentally, Schulze later spoke at a meeting of a Washington, D.C., branch of the Society for Parapsychology about this case. That information made its way to the press, and the published Schulze interview led to the leaking of the exorcism story by Catholic sources. Studying at Georgetown at that time, William Peter Blatty read the story in the Washington Post and years later used it as inspiration for The Exorcist.)

On Schulze's advice, the family went to a local priest, Father E. Albert Hughes, who "gave them a bottle of holy water and candles and sent them on their way," Allen said.

Hughes later asked the arch­bishop of Washington, D.C., for permission to perform an exorcism on the boy. That attempt ended when the boy broke off a piece of a spring from the mattress he was strapped to and slashed Hughes "from shoulder to wrist," Allen said.

The boy's mother, a St. Louis native, suggested a change of scenery. After several incidents of scratches appearing on the boy's body without apparent cause, the word "LOUIS" emerged on his rib cage. The family took this as con­firmation: They should take the boy to St. Louis.

The boy ended up staying in a house with a relative who had attended Saint Louis University. One of her professors was Father Bishop, who became one of sev­eral Jesuits to participate in the exorcism and kept the day-by-day account on which Allen's book is based. Bishop talked to his friend William Bowdern, S.J. After both men consulted with Paul Reinert, S.J., then president of Saint Louis University, and St. Louis Archbishop Joseph Ritter, all agreed that an exorcism would be performed according to the Roman Ritual. It was something that Bowdern, who was chosen to be the lead exorcist, knew little about.

"Father Halloran said the first thing Bowdern did was hit the books," Allen said. "He would have learned something about it while becoming a Jesuit, but there isn't much call for exorcism to the modern-day priest. But Bowdern was a veteran of World War II, he'd been in combat -- so he was a combination of a religious man who was very tough."

The process ended up taking more than a month, during which Bowdern fasted. Several priests, Alexian Brothers and family members participated in or witnessed the rite, which  always began in the evening.

"The pattern was that the boy would act normally during the day, and then he would put on his pajamas and go to bed, and go into a trance and start screaming and yelling and acting wild," Allen said. In the morning, the boy apparently never remem­bered what transpired the night before.

The exorcism continued on almost a nightly basis, even though the boy seemed to be get­ting worse. The priests asked his family for permission to teach him about Catholicism and con­vert him as a way to strengthen the fight against the supposed demonic possession. As he got closer to conversion and making his first holy Communion, his episodes become increasingly violent.

On April 18, the day after Easter Sunday, the exorcism appeared to have succeeded. An entry from Bishop's diary reads: "Since Monday at 11 p.m. there have been no indications of the presence of the devil."

The boy left St. Louis several days later and went on to lead an otherwise normal life; he mar­ried around 1970, had children and never experienced anything like possession again, according to the Jesuits and Alexians who "kept track of him," Allen said.

None of the exorcism's eye­witnesses ever publicly revealed the details of the incident, out of respect for the boy's privacy. But in the words of Jesuit historian and scholar John Padberg, S.J., who also participated in the University's exorcism panel with Allen last October, "It's too good a story not to tell people about it!"

And so, it continues ...


The exorcism of 1949 - made famous by the 1971 bestseller by William Peter Blatty, The Exorcist, and the 1973 horror film by the same name - has become part of Saint Louis University legend. Here are the questions most frequently asked about the exorcism.

Where did the exorcism take place? The fourth floor of DuBourg Hall?

"The exorcism encompassed a lot of time but also geography," Allen said. The rite was started at the boy's relatives' house in a northwest St. Louis suburb, which many say was Bel-Nor. After several nights of disruption to the family, the team moved to Alexian Brothers Hospital in south St. Louis city. (Allen said the Jesuits chose Alexian Brothers for the hospital's reputed discretion; it had served as a rehabilitative facility for alcoholic priests.) After a short time at the rectory of the St. Francis Xavier College Church on SLU's campus -- where the boy converted to Catholicism (from Evangelical Lutheranism) -- the group moved back to Alexian Brothers, where the final days of the exorcism were carried out. That hospital building was razed in 1978. The College Church rectory was torn down in 1966 to make way for the current rectory.

Who was "Robbie Mannheim"?

"Robbie Mannheim" was Allen's alias for the 13-year-old boy at the center of the exorcism story; the Catholic Church referred to him as "Roland Doe." None of the eyewitnesses publicly revealed the boy's true identity, and Allen never disclosed the name from the unedited diary.The Jesuits and Alexians kept track of him, though, Allen said; Robbie married around 1970, had children and never suffered anything like possession again. When Allen was researching Possessed, he wrote to Robbie twice. "I never heard back from him, and I have to respect his privacy," he said. "But if he were not alive, I'd know it."

What were the signs of Robbie's demonic possession? Did he rotate his head 360 degrees and projectile vomit, as in The Exorcist movie?

According to Bishop's diary, before the exorcism began, the signs were obvious but not really violent: scratching sounds coming from the walls and floor, movement of a mattress and other objects, scratch marks on Robbie's skin. During the exorcism ritual, Robbie exhibited much more violent and inexplicable behaviors, including apparent seizures, many scratches and "brands," spitting at the priests and family members present, shouting and laughing fiendishly, using "abusive and dirty" language, urinating and singing phrases from songs he didn't seem to know while not possessed, including "Old Man River," "Blue Danube" and the hymn "Old Rugged Cross."

Was Robbie possessed by Satan?
It isn't possible to prove definitively whether Robbie was possessed, Allen said; the boy might have been mentally ill or perhaps the victim of something "paranormal," as many have speculated. Allen said Halloran never was certain about what was wrong with the boy but was most concerned that Robbie was "scared, confused and caught up in something he didn't understand." Bowdern told William Peter Blatty, "The case in which I was involved was the real thing. I had no doubt about it then, and I have no doubt about it now."
