The primary exorcism took place in August 1928 at the Franciscan Convent in Earling. Father Theophilus Riesinger, a renowned exorcist from the Society of the Precious Blood, was summoned. He kept a detailed Latin diary, later translated and published, which serves as the primary source for the events.
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 of anna ecklund
In the annals of American demonology, few cases rival the intensity and duration of the possession and exorcism attributed to Anna Ecklund. For over a decade, Ecklund allegedly exhibited classic signs of demonic possession: aversion to sacred objects, glossolalia, superhuman strength, clairvoyance, and violent outbursts. The final series of exorcisms in 1928, led by Father Theophilus Riesinger, lasted 23 days and drew national attention. This paper does not seek to validate or dismiss the supernatural claims but instead analyzes the case as a nexus of religious faith, folk hysteria, and pre-modern psychiatric treatment.

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. Anna Ecklund was born Anna Schlegel in 1882
