Jack Parsons—chemist, co-founder of the Jet Propulsion Laboratory (JPL), disciple of Aleister Crowley, and subject of FBI surveillance—is a figure suspended between science and the occult. His private musings and unsealed documents reveal an extraordinary intellect maneuvering through the complex web of brilliance, deception, and distrust during the shadowy era of the early Cold War.
For decades, Parsons has been dismissed as a footnote, a curiosity, or a cautionary tale. Yet his legacy runs deep—his contributions are foundational to American rocketry and the space program, even as his occult practices, volatile personal life, and fiery temperament alienated allies and drew government suspicion. Understanding Parsons demands confronting the volatile intersection of genius, heresy, and the human cost of pushing beyond accepted boundaries.
Early Life: The Making of a Rocket Man and Rebel
Born Marvel Whiteside Parsons in Los Angeles in 1914, Parsons was raised in Pasadena, a privileged but unstable childhood marked by his father’s early abandonment. His restless spirit found refuge in science fiction and homemade explosives. Parsons was fascinated by chemistry from a young age, conducting risky experiments that often skirted the edge of safety and authority.
His rebellious streak followed him to the California Institute of Technology (Caltech). Though he lacked a formal degree, his natural aptitude made him central to Pasadena’s burgeoning rocketry scene. However, Parsons’ unorthodox methods clashed with institutional rules. According to multiple accounts, he was expelled—or compelled to leave—after an incident where he allegedly blew up a campus toilet with homemade explosives. Whether fully accurate or exaggerated, the story underscores the tension between his unruly mind and academic expectations.
By the late 1930s, alongside Frank Malina and Theodore von Kármán, Parsons co-founded the Caltech rocket research group that evolved into JPL. His innovations in solid and liquid rocket fuels, especially Jet-Assisted Take-Off (JATO) technology, proved revolutionary and critical to World War II aviation. Parsons once wrote:
“The rocket stands as the supreme symbol of man’s creative power—his will to conquer matter and rise above it.”
This vision extended beyond science; to Parsons, rocketry was a means of transcending human limits.
Ritual in the Laboratory: Science and Sorcery Collide
Parsons rejected the conventional divide between science and occultism. To him, magick was:
“The science and art of causing change to occur in conformity with will.”
He added,
“The magician must be an explorer, not content with illusions; a scientist of the soul as well as of nature.”
In 1941, Parsons married Helen Northrup but soon became deeply involved with Aleister Crowley’s Ordo Templi Orientis (OTO), assuming leadership of the Pasadena Agape Lodge. Though Parsons never met Crowley—who died in England in 1947—he became a devoted follower through Crowley’s writings and the OTO’s rituals.
Parsons’ Pasadena mansion on Orange Grove Avenue became a vortex of ritual, experimentation, and sexual liberation—a lifestyle sharply at odds with mainstream America. Parsons wrote:
“No man can be free unless he accepts the burden of his own will.”
Yet this freedom carried consequences. Parsons’ affair with Helen’s sister, Sara “Betty” Northrup, fractured the lodge and his family relationships, deepening his isolation.
Meeting L. Ron Hubbard and the Babylon Working
In Pasadena circa 1945, Parsons met L. Ron Hubbard was a struggling pulp fiction writer with a keen interest in mysticism. Hubbard ingratiated himself quickly, joining the Agape Lodge and partnering with Parsons on occult rituals, including the infamous Babylon Working.
In 1946, Parsons conducted the Babylon Working—a series of sex-magick ceremonies intended to summon an elemental“Scarlet Woman,” a key figure in Thelemic belief. Parsons trusted Hubbard both ritually and financially.
The trust was shattered when Hubbard absconded with Parsons’ lover, Betty, and a large portion of Parsons’ money. Parsons bitterly reflected:
“Worse than open enemies are false friends who betray not only the man but his vision.”
The betrayal left Parsons financially broken and emotionally fractured, intensifying his personal and spiritual crises.
Under Government Eyes: The FBI Files
Parsons’ radical spirituality, occult ties, and access to sensitive rocket technology drew FBI scrutiny during the early Cold War. His declassified files describe him as:
“A potential subversive” — not for communist sympathies, but because the Bureau feared his knowledge might be passed to foreign powers such as Israel or the Soviet Union.
An FBI memo stated:
“Subject’s unorthodox beliefs and practices, combined with his access to sensitive military technology, make him a security concern.”
Parsons wrote of his mistrust toward institutional authority:
“The Church, the State, and society pretend to protect us, but in truth they are prisons for the spirit.”
His defiance and personal freedom put him at odds with a government demanding secrecy and conformity.
Death in the Garage Lab: Accident or Something Else?
On June 17, 1952, Parsons died in a violent explosion in his home laboratory, officially ruled an accident caused by spilled fulminate of mercury. But speculation has lingered: suicide, murder, or tragic mishap?
Friends recalled Parsons in his last months as “deeply unsettled”—isolated by financial ruin, personal betrayals, and constant government surveillance.
Erased and Remembered: The Complex Legacy
Despite his foundational role in American rocketry, Parsons was largely omitted from official histories during the Cold War. His occultism and personal chaos were liabilities in a period that demanded sanitized heroes.
Yet the Jet Propulsion Laboratory and the U.S. space program stand as monuments to Parsons’ technical genius. His own words endure:
“Courage is not the absence of fear but the refusal to let fear rule.”
Jack Parsons’ life is a cautionary tale: the price of genius unmoored from restraint and grounded truth. At AshesOnAir, we revisit his writings not to romanticize chaos, but to ask what happens when brilliance defies the boundaries society sets—and what costs follow when a man refuses to bend.
