American occultist (1924–1997)
Sara Elizabeth Bruce Northrup Hollister (April 8, 1924 – December 19, 1997) was an American occultist and second wife of Scientologist founder L. Ron Hubbard. She played a major role in the creation of Dianetics, which evolved into the religious movement Scientology. Hubbard would evolve into the leader of the Church of Scientology.
Northrup was a figure in the Pasadena branch of Ordo Templi Orientis (O.T.O.), a secret society led by the English occultist Aleister Crowley, where she was known as "Soror [Sister] Cassap". She joined as a teenager along with her older sister Helen. From 1941 to 1945 she had a turbulent relationship with her sister's husband John Whiteside Parsons, a pioneer in solid-fuel rocketry and head of the Pasadena O.T.O. Although she was a committed and popular member, she acquired a reputation for disruptiveness that prompted Crowley to denounce her as a "vampire." She began a relationship with L. Ron Hubbard, whom she met through O.T.O., in 1945. She and Hubbard eloped, taking with them a substantial amount of Parsons' life savings and marrying bigamously a year later while Hubbard was still married to his first wife, Margaret Grubb.
Northrup played a significant role in the development of Dianetics, Hubbard's "modern science of mental health", between 1948 and 1951. She was Hubbard's personal auditor and along with Hubbard, one of the seven members of the Dianetics Foundation's Board of Directors. However, their marriage was deeply troubled; Hubbard was responsible for a prolonged campaign of domestic violence against her and kidnapped both her and her infant daughter. Hubbard spread allegations that she was a Communist secret agent and repeatedly denounced her to the FBI. The FBI declined to take any action, characterizing Hubbard as a "mental case". The marriage ended in 1951 and prompted lurid headlines in the Los Angeles newspapers. She subsequently married one of Hubbard's former employees, Miles Hollister, and moved to Hawaii and later Massachusetts, where she died in 1997.
Early life.
Northrup was one of five children born to Thomas Cowley, an Englishman working for the Standard Oil Company, and his wife, Olga Nelson, the daughter of a Swedish immigrant to the United States. She was the granddaughter of Russian emigrant Malacon Kosadamanov (later Nelson) who emigrated to Sweden. The couple had three daughters. In 1923 the family moved to Pasadena, a destination said to have been chosen by Olga using a Ouija board. 
Although she later remembered her childhood with warmth, Northrup's upbringing was marred by her sexually abusive father, who was imprisoned in 1928 for financial fraud. She was sexually active from an unusually young age and often said she lost her virginity at the age of ten.
Relationship with Jack Parsons.
In 1933, Northrup's 22-year-old sister Helen met the 18-year-old Jack Parsons, a chemist who went on to be a noted expert in rocket propulsion. Jack Parsons was also an avid student and practitioner of the occult. Helen and Jack were engaged in July 1934 and married in April 1935. Parsons' interest in the occult led in 1939 to him and Helen joining the Pasadena branch of Ordo Templi Orientis (O.T.O.). At age 15, Northrup moved in with sister Helen and her husband Jack, while she finished high school. 
Sara Northrup joined O.T.O. in 1941, at Parsons' urging, and was given the title of Soror [Sister] Cassap. She soon rose to the rank of a second degree member, or "Magician", of O.T.O. In June 1941, at the age of seventeen, she began a passionate affair with Parsons while her sister Helen was away on vacation. When Helen returned, she found Northrup wearing Helen's own clothes and calling herself Parsons' "new wife". Such conduct was expressly permitted by O.T.O., which followed Crowley's disdain of marriage as a "detestable institution" and accepted as commonplace the swapping of wives and partners between O.T.O. members.
Although both were committed O.T.O. members, Northrup's usurpation of Helen's role led to conflict between the two sisters. The reactions of Parsons and Helen towards Northrup were markedly different. Parsons told Helen to her face that he preferred Northrup sexually: "This is a fact that I can do nothing about. I am better suited to her temperamentally – we get on well. Your character is superior. You are a greater person. I doubt that she would face what you have with me – or support me as well." Some years later, addressing himself as "You", Parsons told himself that his affair with Northrup (whom he called Betty) marked a key step in his growth as a practitioner of magick: "Betty served to affect a transference from Helen at a critical period ... Your passion for Betty also gave you the magical force needed at the time, and the act of adultery tinged with incest, served as your magical confirmation in the law of Thelema."
In 1942 Agape Lodge moved into the house at 1003 South Orange Grove Avenue, a rambling mansion next door to the estate of Adolphus Busch. Parsons subdivided the house into 19 apartments which he populated with a mixture of artists, writers, scientists and occultists. She made a striking impression on the other lodgers; George Pendle describes her as "feisty and untamed, proud and self-willed, she stood five foot nine, had a lithe body and blond hair, and was extremely candid." 
Helen was far less sanguine, writing in her diary of "the sore spot I carried where my heart should be", and had furious – sometimes violent – rows with both Parsons and Northrup. She began an affair with Wilfred Smith, Parsons' mentor in O.T.O. and had a son in 1943 who bore Parsons' surname but who was almost certainly fathered by Smith. Northrup also became pregnant but had an abortion on April 1, 1943, arranged by Parsons and carried out by Dr. Zachary Taylor Malaby, a prominent Pasadena doctor and Democratic politician.
Northrup's hostility towards other members of O.T.O. caused further tensions in the house, which Aleister Crowley heard about from communications from her housemates. He dubbed her "the alley-cat" after an unnamed mutual acquaintance told him that Parsons's attraction to her was like "a yellow pup bumming around with his snout glued to the rump of an alley-cat." Concluding that she was a vampire, which he defined as "an elemental or demon in the form of a woman" who sought to "lure the Candidate to his destruction," he warned that Northrup was a grave danger to Parsons and to the "Great Work" which O.T.O. was carrying out in California.
Similar concerns were expressed by other O.T.O. members. O.T.O.'s US head, Karl Germer, labeled her "an ordeal sent by the gods". Her disruptive behavior appalled Fred Gwynn, a new O.T.O. member living in the commune at 1003 South Orange Grove Avenue: "Betty went to almost fantastical lengths to disrupt the meetings [of O.T.O.] that Jack did get together. If she could not break it up by making social engagements with key personnel she, and her gang, would go out to a bar and keep calling in asking for certain people to come to the telephone."
Relationship with L. Ron Hubbard.
In August 1945, Northrup met L. Ron Hubbard for the first time. He had visited 1003 South Orange Grove Avenue at the behest of Lou Goldstone, a well-known science fiction illustrator, while on leave from his service in the US Navy. Parsons took an immediate liking to Hubbard and invited him to stay in the house for the duration of his leave. Hubbard soon began an affair with Northrup after beginning "affairs with one girl after another in the house." He was a striking figure who habitually wore dark glasses and carried a cane with a silver handle, the need for which he attributed to his wartime service: as Northrup later put it, "He was not only a writer but he was the captain of a ship that had been downed in the Pacific and he was weeks on a raft and had been blinded by the sun and his back had been broken." She believed all of it, though none of his claims of wartime action or injuries were true.
Parsons was deeply dismayed but tried to put a brave face on the situation, informing Aleister Crowley:
 ;templatestyles src="Template:Blockquote/styles.css" / ;About three months ago I met Captain "[sic]" L. Ron Hubbard, a writer and explorer of whom I had known for some time … He is a gentleman; he has red hair, green eyes, is honest and intelligent, and we have become great friends. He moved in with me about two months ago, and although Betty and I are still friendly, she has transferred her sexual affection to Ron.
 ;templatestyles src="Template:Blockquote/styles.css" / ;
Hubbard became Parsons' "magical partner" for a sex magic ritual that was intended to summon an incarnation of a goddess. Although they got on well as fellow occultists, tensions between the two men were apparent in more domestic settings. Hubbard and Northrup made no secret of their relationship; another lodger at Parsons' house described how he saw Hubbard "living off Parsons' largesse and making out with his girlfriend right in front of him. Sometimes when the two of them were sitting at the table together, the hostility was almost tangible." Despite the tensions between them, Hubbard, Northrup and Parsons agreed at the start of 1946 that they would go into business together, buying yachts on the East Coast and sailing them to California to sell at a profit. They set up a business partnership on January 15, 1946 under the name of "Allied Enterprises", with Parsons putting up $20,000 of capital, Hubbard adding $1,200 and Northrup contributing nothing. Hubbard and Northrup left for Florida towards the end of April, Hubbard taking with him $10,000 drawn from the Allied Enterprises account to fund the purchase of the partnership's first yacht. Weeks passed without word from Hubbard. Louis Culling, another O.T.O. member, wrote to Karl Germer to explain the situation:
 ;templatestyles src="Template:Blockquote/styles.css" / ;As you may know by this time, Brother John signed a partnership agreement with this Ron and Betty whereby all money earned by the three for life is equally divided between the three. As far as I can ascertain, Brother John has put in all of his money ... Meanwhile, Ron and Betty have bought a boat for themselves in Miami for about $10,000 and are living the life of Riley, while Brother John is living at Rock Bottom, and I mean "Rock Bottom". It appears that originally they never secretly intended to bring this boat around to the California coast to sell at a profit, as they told Jack, but rather to have a good time on it on the east coast.
Germer informed Crowley, who wrote back to opine: "It seems to me on the information of our brethren in California that Parsons has got an illumination in which he has lost all his personal independence. From our brother's account he has given away both his girl and his money. Apparently it is the ordinary confidence trick."
Parsons initially attempted to obtain redress through magical means, carrying out a "Banishing Ritual of the Pentagram" to curse Hubbard and Northrup. He credited it with causing the couple to abort an attempt to evade him:
 ;templatestyles src="Template:Blockquote/styles.css" / ;Hubbard attempted to escape me by sailing at 5 P.M., and I performed a full evocation to Bartzabel [the spirit of Mars or War] within the circle at 8 P.M. At the same time, so far as I can check, his ship was struck by a sudden squall off the coast, which ripped off his sails and forced him back to port, where I took the boat in custody... Here I am in Miami pursuing the children of my folly; they cannot move without going to jail. However I am afraid that most of the money has already been dissipated.
Northrup later recalled that the boat had been caught in a hurricane in the Panama Canal, damaging it too badly to be able to continue the voyage to California. Parsons subsequently resorted to more conventional means of obtaining redress and sued the couple on July 1 in the Circuit Court for Dade County. His lawsuit accused Hubbard and Northrup of breaking the terms of their partnership, dissipating the assets and attempting to abscond. The case was settled out of court eleven days later, with Hubbard and Northrup agreeing
