Robbie Mannheim / St. Louis Exorcism (1949)
The story in one line
a boy known as Robbie Mannheim underwent a real possession case and exorcism in the 1940s.
The basic story
In 1949, Jesuit priests in St. Louis performed a major exorcism on a boy later known under pseudonyms such as Robbie Mannheim and Roland Doe. The primary public source most often cited is the diary of Fr. Raymond Bishop, alongside later Jesuit and university summaries.
Historical setting
The Robbie Mannheim case sits in mid-twentieth-century America, where a family haunting story, clergy notes, and later retellings built the public narrative.
Year
1949
The case file is tied to a 1949 Catholic exorcism carried out in St. Louis after earlier Washington-area episodes.
Main public record

The diary tradition is the named documentary trail most often cited in later summaries of the case.
Lead clergy
William Bowdern, S.J.
Saint Louis University’s summary names Bowdern as the priest who ultimately took the lead in St. Louis.

How the St. Louis case unfolded
Section titled “How the St. Louis case unfolded”The 1949 St. Louis exorcism story did not begin in St. Louis. It began with a boy in distress whose family had already spent time seeking help around Washington before they turned to Catholic clergy in Missouri.[1] By the time the case reached St. Louis, the people around the boy later known under names such as Robbie Mannheim or Roland Doe had become convinced that the disturbances around him might be more than ordinary illness or behavior problems.[1]
Saint Louis University’s historical summaries say Jesuit priest Fr. Raymond Bishop first visited the family, William Bowdern, S.J. later took the lead in the major rite, and Archbishop Joseph Ritter gave permission for the formal exorcism in St. Louis.[1] That matters because this is not just an anonymous ghost story. The public record ties the case to named priests, a named archbishop, and a specific place.[1] [2]
The episode later became famous because it helped inspire the tradition behind The Exorcist.[1] [2]
Public documentation
Section titled “Public documentation”The main reason this case still gets discussed is that it is not preserved only as rumor. It is tied to a Jesuit diary record, especially the notes associated with Fr. Raymond Bishop.[1]
In plain terms, the public trail gives us:
- named clergy
- a known church setting under archdiocesan authority
- a traceable institutional memory at Saint Louis University
- a record closer to the event than most exorcism stories ever get
The Bishop diary and Jesuit institutional record are the main public sources most often cited for the case.[1]
Saint Louis University’s archive features also preserve the public memory of the case by naming the main locations and explaining how the diary record shaped later retellings.[2] [3]
How the case has been interpreted
Section titled “How the case has been interpreted”Modern discussion of the case still leaves several possibilities open:
- severe adolescent distress
- family and religious suggestion
- deliberate trickery in some episodes
- psychiatric or neurological factors not adequately captured in 1949
- a genuinely preternatural case, as the priests believed
The SLU summary itself treats the episode as part of the university’s documented lore and notes that the boy later seems to have gone on to live a normal adult life.[1]
So the main historical point is not that every detail is proven. It is that a formally authorized Catholic exorcism was carried out in St. Louis in 1949 under archdiocesan permission, and that the surviving diary tradition makes this one of the best documented American exorcism cases in public circulation.
