Anna Ecklund was born Anna Schlegel in 1882 in Milwaukee, Wisconsin. According to Church records, her possession began in childhood. A family curse was suspected, stemming from her father’s affair with a woman alleged to be a witch. By 1912, at age 30, Anna was living on a farm near Earling, Iowa, when symptoms became unmanageable. The local pastor, Father Joseph Steiger, requested permission from Bishop Edmond Heelan of Sioux City to perform an exorcism. The first documented exorcism occurred in 1912, performed by Father Henry Rieker. It was deemed incomplete.
The exorcism raises significant ethical questions. Prolonged restraint, sleep deprivation, and psychological pressure (convincing a person they are inhabited by demons) could be classified as torture by modern standards. Medical notes from the time indicate that Ecklund was examined by a physician who found no organic cause—but no psychiatric evaluation was performed. The case highlights the danger of conflating religious ritual with medical treatment. the exorcism of anna ecklund
This paper provides a comprehensive analysis of the exorcism of Anna Ecklund (a pseudonym for Anna Ecklundt, born Anna Schlegel), which occurred primarily in Earling, Iowa, between 1912 and 1928. The case is one of the most extensively documented Roman Catholic exorcisms in American history. This study examines the historical context, the procedural methods employed by Jesuit priests, the reported phenomena, and the subsequent psychological and sociological interpretations. By comparing primary sources, such as the diaries of Father Theophilus Riesinger, with modern clinical understandings of dissociative disorders and suggestion, this paper argues that the Ecklund case serves as a critical artifact illustrating the early 20th-century clash between religious metaphysics and emerging psychiatric frameworks.
