Sylvan Muldoon (1903–1969) was an American writer and early popularizer of theories of astral projection. He reported his first such experience at the age of twelve while attending a Spiritualist camp in Iowa, an event that shaped his lifelong interest in psychic phenomena.

Muldoon later collaborated with the psychical researcher Hereward Carrington to publish several influential works on the subject, including The Projection of the Astral Body (1929), The Case for Astral Projection (1936), and The Phenomena of Astral Projection (1951). These books helped popularize the idea that a non-material “astral body” could separate from the physical body and travel independently.

In addition to these collaborations, Muldoon authored several works on psychic experiences and paranormal themes. His writings became influential within twentieth-century occult and parapsychological literature, and later scholars have noted similarities between his descriptions of astral projection and concepts developed by L. Ron Hubbard.

Hereward Carrington (1880 –1958) was a British‑born American investigator of psychic phenomena and prolific author whose work helped shape early twentieth‑century psychical research. He became involved with the Society for Psychical Research, eventually writing more than 100 books on topics including the paranormal, spiritualism, conjuring, and alternative medicine.

Carrington investigated many high‑profile cases of apparent psychic ability, including mediumship and poltergeists, and founded the American Psychical Institute to study such phenomena; he later collaborated with authors like Sylvan Muldoon on works about out‑of‑body experiences.

In addition to his parapsychological work, Carrington promoted unconventional health theories such as fruitarianism and fasting, reflecting his broader interest in vitalist explanations of mind and body.
