Spielrein sometimes is regarded as having been the inspiration for Jung's conception of the anima, in part due to a reference Jung made 50 years later in "Memories, Dreams, Reflections"—the biographical memoir compiled and edited by Aniela Jaffé—to an imaginatively encountered interior feminine voice that awakened his awareness of the interior anima. He recounted, it was "the voice of a patient ... who had a strong transference to me". However, in the unpublished transcript of Jung's comments recorded by Aniela Jaffé in 1957, Jung made it clear this woman was Maria Moltzer and not Spielrein. Nonetheless, Lance Owens has documented that the relationship with Spielrein was indeed crucial to Jung's evolving understanding of what he much later termed the anima.
