Ralph Brewster Allison

It is with a heavy heart that we acknowledge the passing of Dr. Ralph B. Allison, a pioneering and often controversial figure in the field of psychiatry, who departed on May 17, 2025, just days after his 94th birthday. Born on May 13, 1931, Dr. Allison dedicated his life to understanding and treating complex dissociative disorders, leaving an indelible mark on the landscape of mental health.

A board-certified forensic psychiatrist, Dr. Allison began his specialized work with dissociative patients in 1972, at a time when conditions like Multiple Personality Disorder (MPD), now known as Dissociative Identity Disorder (DID), were widely misunderstood and frequently debated. He became a prominent voice in the field, developing new techniques in both diagnosis and treatment for MPD.

One of Dr. Allison's most significant contributions was his development and advocacy of the "Inner Self Helper" (ISH) concept. He described the ISH as a guiding, often spiritual, aspect within the human mind that could assist patients in their journey toward integration and psychological wholeness. This unique perspective, which blended traditional psychotherapy with parapsychological insights, distinguished his approach and was extensively explored in his writings and teachings. His work, including his book "Minds in Many Pieces: Revealing the Spiritual Side of Multiple Personality Disorder," delved into the bipartite human mind, the integration of multiple personalities, and the role of what he termed "Essence" (soul or spirit).

Dr. Allison was a prolific author and. he documented his extensive experiences through several books and papers, both published and unpublished.. His influence extended to academia, where he was involved in early American Psychiatric Association courses on MPD. Dr. Allison's willingness to explore the spiritual dimensions of the human psyche, often viewed with skepticism by his peers, underscored his dedication to exploring ways to treat MPD despite resistance. He challenged conventional thinking, opening new avenues for understanding and treatment that will continue to inspire and provoke thought for generations to come. He is remembered by his patients, colleagues, and all those whose lives he touched through his pioneering work.

He is survived by his four adult children, eight grandchildren, and two great-grandchildren. He was married to Mary (Mitzi) Burden for 38 years, and lived in several different locations in California, as he moved for work. After his retirement, he married June Turnquist until her passing. Per his wishes, Dr. Allison’s ashes were scattered over the Pacific Ocean, near Morro Bay. His family will be having a small memorial service on October 18, 2025 to remember his life, his accomplishments, and to say their farewells.
