Jack Parsons
Pioneering rocket engineer, co-founder of the Jet Propulsion Laboratory, and occultist who sought to bridge the worlds of science and magic.
Early Life and Background
Marvel Whiteside Parsons, who preferred to be called Jack, was born on October 2, 1914, in Los Angeles, California. Born into a wealthy family, his early life was marked by the abrupt departure of his father, leaving Jack and his mother to navigate a challenging financial and emotional landscape. This absence would later shape Parsons' complex relationship with authority and his search for father figures in both scientific and magical circles.
As a child, Parsons showed an early and intense fascination with rocketry and science fiction, particularly the works of Jules Verne. By his teenage years, he had begun conducting amateur rocket experiments in his backyard, a pursuit that would shape his professional trajectory. Despite his brilliant mind, Parsons lacked formal higher education, having only briefly attended Pasadena Junior College and Stanford University without completing degrees.
This lack of formal education would simultaneously pose challenges to his scientific recognition while freeing him from conventional academic constraints. It allowed him to pursue radical approaches to rocketry that more traditionally trained engineers might have dismissed. This pattern of existing outside established frameworks would extend to both his scientific work and occult practices.
"I had experienced a period of living that could only be described as magical... I had grown in understanding to the stature of a god, and lived with a goddess, and wrote poetry that was at least the equal of Shelley."
— Jack Parsons, in personal correspondence
Pioneer of Rocket Science
In 1936, Parsons, along with Edward Forman and Frank Malina, approached Theodore von Kármán, director of the Guggenheim Aeronautical Laboratory at the California Institute of Technology (GALCIT), with their ideas on rocket propulsion. Despite their unorthodox backgrounds, von Kármán saw potential in their work and provided them with facilities to conduct research, leading to the formation of what would become known as the "Suicide Squad" due to the dangerous nature of their experiments.
The Birth of JPL
The group's experiments in the Arroyo Seco near Pasadena would eventually lead to the establishment of the Jet Propulsion Laboratory (JPL), now a leading center for space exploration under NASA. Parsons' contributions were fundamental:
- He pioneered the development of solid rocket fuels, solving the critical problem of achieving stable and controllable thrust.
- His innovation of using a composite fuel of asphalt and potassium perchlorate was a breakthrough that made large-scale solid rockets practical.
- This technology directly enabled the development of the JATO (Jet-Assisted Take Off) units crucial for American military aircraft during World War II.
- His work laid the foundation for the solid rocket boosters used in the Space Shuttle program and many other launch vehicles.
As co-founder of the Aerojet Engineering Corporation in 1942 (now Aerojet Rocketdyne), Parsons helped transform theoretical rocket science into a practical, commercial industry. However, as the company became more corporate and military-oriented, Parsons found himself increasingly marginalized due to his unconventional lifestyle and lack of formal credentials.
Scientific Contributions
Parsons' approach to rocket science was characterized by a blend of theoretical insight, practical experimentation, and intuitive innovation:
- Castable Composite Propellants: Parsons developed methods for mixing solid fuels that could be poured into rocket casings, revolutionizing rocket manufacturing.
- Hypergolic Propellants: He contributed to the understanding of self-igniting liquid propellants that remain crucial in spacecraft propulsion.
- Rocket Motor Design: His work on the internal geometry of solid rocket motors improved efficiency and reliability.
- Theoretical Writings: Though less formally educated than his colleagues, Parsons authored several important technical papers on propulsion technology.
Von Kármán later described Parsons as an "excellent chemist and a delightful screwball" whose intuition often led to solutions that more methodical approaches might have missed. This capacity to bridge intuition and technical analysis would become characteristic of Parsons' approach to both science and occultism.
Magical Pursuits
Parallel to his scientific career, Parsons developed an intense interest in occultism and ceremonial magic. In 1939, he joined the Agape Lodge of the Ordo Templi Orientis (O.T.O.), the American branch of the magical order previously led by Aleister Crowley:
The Agape Lodge
Under Parsons' leadership, the Agape Lodge became the most active O.T.O. branch in the world. He turned his mansion at 1003 South Orange Grove Avenue in Pasadena—nicknamed "The Parsonage"—into a center for both occult practice and bohemian culture. The house became a gathering place for science fiction writers, artists, occultists, and freethinkers, creating a unique intersection of scientific, artistic, and magical communities in 1940s California.
Relationship with Crowley
Parsons maintained a complex relationship with Aleister Crowley, who served as his magical mentor from afar. While Crowley recognized Parsons' magical potential, describing him as "the most promising member of the order," he also expressed concerns about Parsons' impulsiveness and lack of discipline. Their correspondence reveals both deep mutual respect and occasional friction as Parsons developed his own magical ideas that sometimes diverged from orthodox Thelemic practice.
Babalon Working
Parsons' most notorious magical operation was the series of rituals he conducted between January and March 1946, known as the "Babalon Working." With the assistance of L. Ron Hubbard (later founder of Scientology), Parsons sought to incarnate an elemental being or "moonchild" that would serve as the earthly vessel for Babalon, the feminine divine force in Thelemic cosmology. These rituals combined ceremonial magic, sex magic, and aspects of Enochian magic developed by John Dee in the 16th century.
The Book of Babalon
Following the Babalon Working, Parsons wrote Liber 49: The Book of Babalon, which he claimed was dictated to him by a praeterhuman intelligence. This text, along with The Manifesto of the Antichrist, represents Parsons' most significant contribution to occult literature. These writings synthesized Thelemic principles with his own visionary experiences and presented a prophetic, apocalyptic framework centered on the imminent manifestation of Babalon as a transformative force in human consciousness.
Synthesis of Science and Magic
What distinguished Parsons from many of his occult contemporaries was his attempt to reconcile magical thinking with scientific rationality. He did not view his scientific and magical pursuits as contradictory but as complementary approaches to understanding and transforming reality:
"The purpose of Magick is to obtain power over yourself, your environment, and the forms and forces of nature. This power comes from knowledge and depends on correct information. A technique must be objectively tested, and the result must be verified, not by belief, but by a rigorous and objective examination of the results."
In his essay "Freedom is a Two-Edged Sword," Parsons articulated a vision of magic as a technology of consciousness that could be subjected to experimental verification, anticipating later developments in chaos magic and scientific approaches to altered states. While his specific synthesis remains controversial, his insistence that magical practices should be compatible with scientific understanding represented an important development in modern occultism.
Personal Life and Controversies
Parsons' personal life was as unconventional as his professional pursuits, reflecting both the progressive and problematic aspects of his character:
Relationships and Community
Parsons' first marriage to Helen Northrup ended when she became involved with L. Ron Hubbard in 1945. Parsons subsequently entered a relationship with Marjorie Cameron, who he believed was the incarnation of Babalon he had summoned during his magical workings. Their relationship, formalized in marriage in 1946, represented for Parsons the union of magical theory and practice. Cameron would go on to become a significant avant-garde artist and occult figure in her own right.
Security Concerns and Blacklisting
Parsons' unconventional lifestyle, occult practices, and associations led to increasing government suspicion during the early Cold War period. In 1948, he lost his security clearance amid allegations of espionage, though no conclusive evidence supported these claims. This effectively ended his career in rocketry at a time when the field was becoming increasingly integrated with military and governmental institutions.
Forced to find alternative employment, Parsons worked various jobs including special effects work for the film industry and consulting on international explosives projects. Though financially strained, he continued his occult practices and writing during this period of professional exile.
Political Views
Parsons espoused a unique libertarian philosophy that emphasized personal freedom, individual rights, and resistance to authoritarianism. His politics were complex, combining elements of:
- Anti-fascism and opposition to McCarthyism
- Advocacy for religious freedom and separation of church and state
- Support for individual liberty in matters of sexuality and consciousness
- Concern about the military-industrial complex's influence on scientific research
These views, alongside his occult practices, made him a target during the Red Scare era, despite his strong anti-communist stance. His essay "Freedom is a Two-Edged Sword" articulates his political philosophy, warning against both right-wing repression and left-wing totalitarianism as threats to individual liberty.
Mysterious Death and Enduring Legacy
On June 17, 1952, at the age of 37, Parsons was killed in an explosion in his home laboratory at 424 Arroyo Terrace in Pasadena. The official verdict ruled the death accidental, concluding that Parsons had dropped a vial of fulminate of mercury. However, the circumstances of his death have fueled speculation among both researchers and conspiracy theorists:
- Suspicious Timing: The explosion occurred the day before Parsons was scheduled to leave for Mexico to establish an explosives factory.
- Expertise Question: Given Parsons' extensive experience handling explosive materials, some find it implausible that he would make such a basic handling error.
- Alternative Theories: Various theories attribute his death to suicide, murder by intelligence agencies concerned about his knowledge, or sabotage by personal enemies.
- Magical Interpretations: Some occultists have suggested that Parsons' death represented a form of magical self-sacrifice in line with his devotion to Babalon.
Scientific Recognition
Despite his foundational contributions to rocketry, Parsons' scientific legacy was initially obscured by his unconventional personal life and the classified nature of much of his work. However, recent decades have seen increasing recognition:
- In 1972, the International Astronomical Union named a crater on the Moon's dark side "Parsons Crater" in his honor.
- JPL, the institution he helped found, has gradually acknowledged his contributions, particularly during its 50th and 75th anniversary celebrations.
- The American Institute of Aeronautics and Astronautics recognized Parsons with a propulsion award named in his honor.
- Modern rocket scientists acknowledge that his innovations in solid propellant chemistry remain fundamental to contemporary rocketry.
Cultural Impact
Parsons has become an increasingly influential figure in popular culture, especially at the intersection of technology, counterculture, and spirituality:
- His life has been the subject of biographies, documentaries, plays, and a television series (Strange Angel).
- In techno-occult circles, he is viewed as a visionary who anticipated the merging of technology and consciousness exploration.
- Contemporary magical traditions, particularly chaos magic, draw inspiration from his experimental approach to occult practice.
- His advocacy for individual liberty in matters of consciousness has influenced psychedelic culture and modern magical movements.
Perhaps most significantly, Parsons embodied the intersection of seemingly contradictory domains: cutting-edge science and ancient esoteric practices, disciplined engineering and artistic experimentation, patriotic service and countercultural rebellion. This integration of opposites makes him a complex symbol for our contemporary world, where the boundaries between technology, spirituality, and art continue to blur.
Parsons himself seemed aware of his liminal position between worlds. In a letter written shortly before his death, he reflected: "I have parted the veil of secrecy covering a great prophet and a great secret. I have accomplished my will which was to be a light-bearer for Babalon and to build a fire for a beacon, a warning, and a testimony."

Science and Magic: The Parsons Synthesis
"The most important element of magical practice is empirical investigation. The magician must be experimental, flexible, and willing to test everything for himself, and to utilize these results in modifying and developing his system."
"The universe is a drama, unfolding in acts and scenes, where consciousness creates reality through will and imagination. The magician and the scientist both manipulate symbols to change reality—one using mathematical equations, the other using ritual and image."
