George Sergius de Mohrenschildt (Russian: Георгий Сергеевич де Мореншильд; April 17, 1911 – March 29, 1977) was a petroleum geologist and professor who befriended Lee Harvey Oswald in the summer of 1962 and maintained that friendship until Oswald's death, two days after the assassination of US President John F. Kennedy. His testimony before the Warren Commission investigating the assassination was one of the longest of any witness.
De Mohrenschildt was born Jerzy Sergius von Mohrenschildt in Mozyr in Tsarist Russia, presently in Belarus (his birthdate was April 4 in the old style Russian Julian calendar). He had an older brother, Dimitri. His wealthy father, Sergey Alexandrovich von Mohrenschildt, was of German, Swedish and Russian descent. De Mohrenschildt's mother, Alexandra, was of Polish, Russian and Hungarian descent. Sergey von Mohrenschildt was a Marshal of Nobility of Minsk Governorate from 1913-1917, and a civil rank of Actual Civil Councilor corresponding to Major General. In 1920, Sergy von Mohrenschildt was arrested by the Bolsheviks shortly after the Russian Revolution for anti-Communist activities. Sergey was sentenced to life in exile in Veliky Ustyug, a town in the North of Russia. De Mohrenschildt later testified to the Warren Commission that while awaiting transport to Veliky Ustyug, Sergey became ill. Two Jewish doctors who treated Sergey in jail advised him to stop eating so he would appear more sickly. The doctors then told the Soviet government that Sergey was too ill to survive the trip to Veliky Ustyug and he should be allowed to stay home to recover under the condition that he check in weekly until he was well enough to be sent to Veliky Ustyug. The Soviet government agreed. After his release, Sergey, his wife and De Mohrenschildt then fled to Poland via a hay wagon (De Mohrenschildt's older brother Dimitri was awaiting execution but was later released in a prisoner exchange in Poland). During their journey, De Mohrenschildt, his father and mother Alexandra contracted typhoid fever. Alexandra died of the disease shortly after the family entered Poland.
After the death of his mother, De Mohrenschildt and his father made their way to Wilno where the family had a six acre estate. De Mohrenschildt graduated from the Wilno gymnasium in 1929 and later graduated from Polish Cavalry Academy in 1931. He went on to earn a Master's Degree at the Institute of Higher Commercial Studies. Having completed a dissertation on the economic influence of the U.S. on Latin America, he received a doctor of science degree in international commerce from the University of Liège in Belgium in 1938.
George de Mohrenschildt immigrated to the United States in May 1938 after which he changed his surname from "von Mohrenschildt" to "de Mohrenschildt". Upon his arrival, British intelligence reportedly told the U.S. government that they suspected he was working for German intelligence. Documents indicate he was under FBI surveillance for much of the 1940s. De Mohrenschildt was hired by the Shumaker company in New York City, which also employed a man named Pierre Fraiss who had connections with French intelligence. According to De Mohrenschildt, he and Fraiss, among their other duties, gathered information about people involved in "pro-German" activities, such as those bidding for U.S. oil leases on behalf of Germany before the U.S. became involved in World War II. De Mohrenschildt testified that the purpose of their data-collection was to help the French out-bid the Germans.
De Mohrenschildt spent the summer of 1938 with his older brother Dimitri von Mohrenschildt on Long Island, New York. Dimitri was a staunch anti-Communist and member of the OSS and one of the founders of the CIA's Radio Free Europe and Amcomlib (a.k.a., Radio Liberty) stations. His contacts included top officials of the CIA. (Dimitri died at the age of 100 in 2002.)
While in New York, De Mohrenschildt became acquainted with the Bouvier family, including young Jacqueline Bouvier, future wife of John F. Kennedy. Jacqueline grew up calling De Mohrenschildt "Uncle George" and would sit on his knee. He became a close friend of Jacqueline's aunt Edith Bouvier Beale.
De Mohrenschildt dabbled in the insurance business from 1939 to 1941, but failed to pass his broker's examination. In 1941, he became associated with Film Facts in New York, a production company owned by his cousin Baron Maydell who was said to have pro-Nazi sympathies. (De Mohrenschildt denied any Nazi sympathies of his own, claiming he helped raise money for the Polish resistance.) De Mohrenschildt made a documentary film about resistance fighters in Poland. However, when the United States entered World War II, his application to join the Office of Strategic Services (OSS) was rejected. According to a memo by former CIA director Richard Helms, De Mohrenschildt "was alleged to be a Nazi espionage agent."
In 1942, De Mohrenschildt married a teenager named Dorothy Pierson. They had a daughter, Alexandra (known as "Alexis") and divorced in early 1944. In 1945, De Mohrenschildt received a master's degree in petroleum geology from the University of Texas.
Dallas, Oswald and Haiti
After the end of World War II, De Mohrenschildt moved to Venezuela where he worked for Pantepec Oil, a company owned by the family of William F. Buckley. In 1947, he married Phyllis Washington, the daughter of a diplomat with the State Department. They divorced in 1949. That same year, De Mohrenschildt became a U.S. citizen. In 1950, he launched an oil investment firm with his step-nephew Edward Hooker with offices in New York City, Denver and Abilene. In 1951, De Mohrenschildt married physician Wynne "Didi" Sharples. The following year, the couple settled in Dallas, Texas where De Mohrenschildt took a job with oilman Clint Murchison as a petroleum geologist. De Mohrenschildt and his third wife had two children, a son and a daughter, both of whom were born with cystic fibrosis (the couple's son died of the disease in 1960 as did their daughter in 1973). De Mohrenschildt and Sharples divorced in 1957.
Described as sophisticated and articulate, De Mohrenschildt became a respected member of the Russian émigré community in Dallas. He joined the Dallas Petroleum Club, was a member of the Dallas Council on World Affairs, and taught at a local college. One of De Mohrenschildt's longtime friends, offshore oil engineer George Kitchel, told the FBI that De Mohrenschildt counted among his good friends oil barons Clint Murchison, H.L. Hunt, John W. Mecom, Sr., and Sid Richardson. De Mohrenschildt also joined the right-wing Texas Crusade for Freedom whose members included Earle Cabell, Everette DeGolyer, Harold Byrd and Ted Dealey.
In 1957, De Mohrenschildt went to Yugoslavia to conduct a geological field survey for the U.S. State Department sponsored International Cooperation Administration. While in Yugoslavia, he was accused by the authorities there of making drawings of military fortifications. After returning to the United States, De Mohrenschildt was debriefed by the CIA, both in Washington and in Dallas.
De Mohrenschildt married his fourth wife, former dancer and model Jeanne LeGon, in 1959. LeGon (born Eugenia Fomenko) was the daughter of the director of the Chinese Far East Railway who was later killed by Communists. From late 1960 and into 1961, he and his wife toured Central America and the Caribbean. His "walking trip" through Central America was made to recover from the grief of his only son having died in 1960 of Cystic Fibrosis. However, de Mohrenschildt did submit a written report of his trip to the U.S. State Department, and a photograph shows De Mohrenschildt meeting with the American ambassador to Costa Rica.
Lee Harvey Oswald and his Russian-born wife Marina Oswald were introduced to De Mohrenschildt in the summer of 1962 in Fort Worth, Texas. De Mohrenschildt testified to the Warren Commission in 1964 that he had met the Oswalds through George Bouhe. When he asked “Do you think it is safe for us to help Oswald”, Bouhe said he had checked with the FBI. De Mohrenschildt also stated that he believed he had discussed Oswald with Max Clark, whom be believed was connected with the FBI and J. Walton Moore, whom De Mohrenschildt described as "a Government man — either FBI or Central Intelligence", and who had debriefed De Mohrenschildt several times following De Mohrenschildt's travels abroad, starting in 1957. (According to a CIA classified document, obtained by House Select Committee on Assassinations, J. Walton Moore was an agent of the CIA's Domestic Contacts Division in Dallas.) De Mohrenschildt asserted that shortly after meeting Oswald, he asked Moore and Fort Worth attorney Max E. Clark about Oswald to reassure himself that it was "safe" for the De Mohrenschildts to assist Oswald. De Mohrenschildt testified that one of the persons he talked to about Oswald told him that Oswald "seems to be OK," and that "he is a harmless lunatic." However, De Mohrenschildt was not exactly sure who it was who told him this. (When interviewed in 1978 by the House Select Committee on Assassinations, J. Walton Moore said that he had no recollection of any conversation with De Mohrenschildt concerning Oswald.) During this period, tens of thousands of American citizens were routinely debriefed by the CIA after traveling to communist countries such as Yugoslavia, as De Mohrenschildt was.) However, Moore had dined several times at De Mohrenschildt's home in Dallas since then. De Mohrenschildt devoted a large part of his next seven months to arranging — and rearranging — each of the Oswalds' lives. After returning home from a weekend trip to Houston, De Mohrenschildt became aware that someone had broken into his home and copied his personal papers and other documents. At the time, he also had a manuscript that Lee Harvey Oswald had given him to read and realized this document might also have been photocopied in the search. His primary concern was that the CIA was behind the break-in. According to De Mohrenschildt, J. Walton Moore flatly denied the CIA was involved in any way.
In October 1962, De Mohrenschildt told Oswald that he would have a better chance of finding work in Dallas, after Oswald informed De Mohrenschildt that he had lost his job in nearby Fort Worth, Texas. Oswald was soon hired by the Dallas photographic firm of Jaggars-Chiles-Stovall. George de Mohrenschildt's wife and daughter would later say that it was George de Mohrenschildt who secured the job at Jaggars-Chiles-Stovall for Oswald.
On April 14, 1963, George de Mohrenschildt and his wife, Jeanne, visited the Oswalds' apartment. As Oswald's wife, Marina was showing Jeanne around the apartment, they discovered Oswald's rifle leaning against the wall inside a closet. Jeanne told George that Oswald had a rifle, and George joked to Oswald, "Were you the one who took a pot-shot at General Walker?" (General Edwin Walker was a conservative activist who George de Mohrenschildt said he "knew that Oswald disliked.") When later asked by the Warren Commission about Oswald's reaction to his question, George de Mohrenschildt said that Oswald "smiled at that." In an interview with Edward Jay Epstein, De Mohrenschildt claimed to have been in touch with the CIA about Oswald’s attempted assassination of General Walker. "I spoke to the CIA both before and afterwards. It was what ruined me."  The Warren Commission concluded that on April 10, 1963, Oswald had attempted to kill General Walker.
De Mohrenschildt moved to Haiti in June. He never saw Oswald again. At the time of the Kennedy assassination, he was attending a party when a radio broadcast the news. According to those present with him at the party, De Mohrenschildt paled and blurted out, "Could it have been Oswald? Was he involved?" As he became the center of attention, he continued, "The FBI in Dallas and the FBI in Fort Worth told me he was harmless." De Mohrenschildt had begun to talk about Oswald's possible connection to the assassination more than one hour before the rest of the world was to hear his name broadcast.
After Kennedy was assassinated, De Mohrenschildt testified before the Warren Commission in April 1964. (For this testimony in the hearing record, see Testimony of George S. de Mohrenschildt.) According to Colonel L. Fletcher, then chief Pentagon-to-CIA liaison officer, De Mohrenschildt had several private lunches with former CIA Director and Warren Commission member Allen Dulles while testifying before the Warren Commission. In November 1966, de Mohrenschildt left Haiti and returned to Dallas. During 1967, New Orleans District Attorney Jim Garrison interviewed Jeanne and George de Mohrenschildt as part of Garrison's prosecution of Clay Shaw. Garrison said that both de Mohrenschildts insisted that Oswald had been the scapegoat in the assassination of President Kennedy. Garrison concluded from his conversation with the de Mohrenschildts that George de Mohrenschildt had been one of Oswald's unwitting "baby-sitters... assigned to protect or otherwise see to the general welfare of [Oswald]." Garrison concluded from his conversation with the de Mohrenschildts that George de Mohrenschildt had been one of Oswald's unwitting "baby-sitters assigned to protect or otherwise see to the general welfare of [Oswald]." De Mohrenschildt told Willem Oltmans "I am very much afraid of this investigation by Jim Garrison because I believe that he is on the right track." De Mohrenschildt's son-in-law, Gary Taylor, testified before the Warren Commission that "if there was any assistance or plotters in the assassination that it was, in my opinion, most probably the De Mohrenschildt's." A friend of the De Mohrenschildt's, Mrs. Igar Voshinin, testified that "George repeatedly hinted that he was doing some service for the State Department."
Later life and death
George and Jeanne de Mohrenschildt obtained a divorce in Dallas, Texas on April 3, 1973, after nearly fourteen years of marriage. It was not reported in the local newspapers, and the couple continued to present themselves as husband and wife.[a]
On September 17, 1976, the CIA requested that the FBI locate De Mohrenschildt, because he had "attempted to get in touch with the CIA Director." On September 5, 1976, De Mohrenschildt had written a letter to the Director of the Central Intelligence Agency, George H. W. Bush, asking for his assistance. He was acquainted with the Bush family; George HW Bush had roomed with De Mohrenschildt's nephew, Edward G. Hooker, at Phillips Academy in Andover, Massachusetts. The letter said:
You will excuse this hand-written letter. Maybe you will be able to bring a solution to the hopeless situation I find myself in. My wife and I find ourselves surrounded by some vigilantes; our phone bugged; and we are being followed everywhere. Either FBI is involved in this or they do not want to accept my complaints. We are driven to insanity by the situation. I have been behaving like a damn fool ever since my daughter Nadya died from [cystic fibrosis] over three years ago. I tried to write, stupidly and unsuccessfully, about Lee H Oswald and must have angered a lot of people — I do not know. But to punish an elderly man like myself and my highly nervous and sick wife is really too much. Could you do something to remove the net around us? This will be my last request for help and I will not annoy you any more. Good luck in your important job. Thank you so much.
George Bush responded:
Let me say first that I know it must have been difficult for you to seek my help in the situation outlined in your letter. I believe I can appreciate your state of mind in view of your daughter's tragic death a few years ago, and the current poor state of your wife's health. I was extremely sorry to hear of these circumstances. In your situation I can well imagine how the attentions you described in your letter affect both you and your wife. However, my staff has been unable to find any indication of interest in your activities on the part of Federal authorities in recent years. The flurry of interest that attended your testimony before the Warren Commission has long subsided. I can only speculate that you may have become "newsworthy" again in view of the renewed interest in the Kennedy assassination, and thus may be attracting the attention of people in the media. I hope this letter had been of some comfort to you, George, although I realize I am unable to answer your question completely.
On November 9, 1976, Jeanne had De Mohrenschildt committed to a mental institution in Texas for three months, and listed in a notarized affidavit four previous suicide attempts while he was in the Dallas area. In the affidavit she stated that De Mohrenschildt suffered from depression, heard voices, saw visions, and believed that the CIA and the Jewish Mafia were persecuting him. He was released at the end of the year, however.
According to Dutch journalist Willem Oltmans, a "serious and famous Dutch clairvoyant," named Gerard Croiset, had a vision in 1967 of a conspirator who had manipulated Oswald; his description led Oltmans to De Mohrenschildt, and the two stayed in touch. In 1977, Oltmans went to Texas and brought De Mohrenschildt to the Netherlands. Oltmans claimed that he rescued De Mohrenschildt from a mental institution to bring him to the "famous" clairvoyant, Croiset. According to Oltmans, Croiset agreed that De Mohrenschildt was the man he saw in his vision.
Oltmans says that after De Mohrenschildt arrived in the Netherlands, he invited him out with some Russian friends. They went to Brussels and had plans to go to Liège, a city in the French-speaking part of Belgium. Oltmans owned a house not far from Liège in the countryside. Upon returning to Brussels, De Mohrenschildt went for a short walk from which he failed to return. He had earlier agreed to meet Oltmans and his friends for lunch. Oltmans waited for him but he did not come back.
On March 16, 1977, De Mohrenschildt returned to the United States from his trip. His daughter talked with him at length and found him to be deeply disturbed about certain matters and had expressed a desire to kill himself. On March 29, De Mohrenschildt gave an interview to author Edward Jay Epstein, during which he claimed that in 1962, Dallas CIA operative J. Walton Moore and one of Moore’s associates handed him the address of Lee Harvey Oswald in nearby Fort Worth and then suggested that deMohrenschildt might like to meet him. Some help from the U.S. Embassy in Haiti would be greatly appreciated by him, he suggested to Moore. "I would never have contacted Oswald in a million years if Moore had not sanctioned it," De Mohrenschildt said. "Too much was at stake." On the same day as the Epstein interview, De Mohrenschildt received a business card from Gaeton Fonzi, an investigator for the House Select Committee on Assassinations, telling him that he would like to see him. The HSCA considered him a "crucial witness". That afternoon, De Mohrenschildt was found dead from a self-inflicted shotgun wound to the head in a house where he was staying in Manalapan, Florida. The coroner's verdict was suicide.
In the book Killing Kennedy, reporter Bill O'Reilly claimed he was knocking at De Mohrenschild's front door as he heard the shotgun blast that marked the suicide. This claim, however, has since been proven false. A contemporaneously made phone call recording between O'Reilly and Fonzi confirms the inaccuracy of O'Reilly's claim.
House Select Committee on Assassinations
On April 2, 1977, Willem Oltmans told the House Select Committee on Assassinations that De Mohrenschildt had implicated himself in the conspiracy to kill President Kennedy. And Pat S. Russell, who was De Mohrenschildt's attorney said "I definitely feel there was a conspiracy and that definitely was the opinion of George."  Oltmans testified for three hours behind closed doors and told the committee that De Mohrenschildt told him he had discussed the assassination of Kennedy with Oswald from A to Z. "De Mohrenschildt told me that Oswald acted at his (De Mohrenschildt's) instructions and that he knew Oswald was going to kill Kennedy," Oltmans said. Although Oltmans had given information to the Committee shortly before, De Mohrenschildt's death had released Oltmans from his promise not to divulge certain information. Oltmans revealed that De Mohrenschildt, whom he had known for ten years, had told him that there had been a conspiracy to assassinate Kennedy and that he had played a role in the conspiracy. De Mohrenschildt said that CIA and FBI personnel were involved as well. Oltmans also stated that De Mohrenschildt was "petrified" that he would "be killed or disappear like others who were connected with the Kennedy assassination."
On July 6, 1978, Joseph Dryer told the House Select Committee on Assassinations that he and de Mohrenschildt were associated with a woman named Jacqueline Lancelot. Dryer's relationship with Lancelot included passing messages for her to people in the United States whom Dryer assumed were connected in some way to the CIA. Dryer said in the interview that Lancelot told him shortly after the Kennedy assassination that a "substantial" sum of money, $200,000 or $250,000, had been deposited in de Mohrenschildt's account. Dryer said that de Mohrenschildt claimed he came to Haiti to scout for oil, but Dryer stated that "I could never figure out what he did." Dryer expressed the belief that de Mohrenschildt had "some intelligence connection".
Congressional researcher Gaeton Fonzi noted that in late 1963 "several large deposits popped up in de Mohrenschildt's Haitian bank account including one for two hundred thousand dollars from a Bahamian bank. This occurred when de Mohrenschildt and Charles were 'supposedly' running a sisal plantation, a derelict operation they never went near."
In a 1976 CIA internal memo regarding De Mohrenschildt, Director George H. W. Bush stated: "At one time he had/or spent plenty of money."
Another backyard photo
On April 1, 1977, Jeanne de Mohrenschildt gave the House Select Committee on Assassinations a print of a photograph showing Lee Harvey Oswald standing in his Dallas backyard holding two newspapers and a rifle, and with a pistol on his hip – a photograph taken by Oswald's wife Marina. While similar to other prints which had been found among Oswald's effects on November 23, 1963, the existence of this particular print was previously unknown. On the back of that print was written To my friend George from Lee Oswald, and the date “5/IV/63” (5 April 1963). along with the words “Copyright Geo de M”' and a Russian phrase translated as “'Hunter of fascists, ha-ha-ha!” Handwriting specialists later concluded that the words “To my friend George…” and Oswald's signature were written by Lee Harvey Oswald, but could not determine whether the rest was the writing of Lee Oswald, De Mohrenschildt, or Marina Oswald. De Mohrenschildt assumed that Marina had written it sarcastically.
De Mohrenschildt wrote in his manuscript (reference and pages cited above) that he had missed Oswald's photograph in packing for the move to Haiti in May, 1963, and this was why he had not mentioned it to the Warren Commission (though he had noted in his manuscript that Oswald had a rifle in April 1963, and scoffed to Oswald that he had missed General Walker, remembering that Oswald had blanched at the joke). According to De Mohrenschildt, the photo was not found among his stored papers until he and his wife found it in February 1967. When analyzed by the HSCA in 1977, this photo turned out to be a first generation print of the backyard photo already known to the Warren Commission as CE-133A, and which had probably been taken on March 31, 1963.
Jeanne de Mohrenschildt also gave the HSCA committee a copy of a draft manuscript called I Am a Patsy! I Am a Patsy! which George de Mohrenschildt had completed in the summer of 1976 about his relationship with his "dear, dead friend" Oswald, wherein he said that the Oswald he knew was rarely ever violent and would not have been the sort of person to have killed John F. Kennedy. In part this judgment was based on De Mohrenschildt's estimation of Oswald's political views and Kennedy's liberal ideas. Until 2014 the memoir had never been published as a stand-alone book but the entire typescript was published as an appendix in the HSCA report.
The primary focus of De Mohrenschildt’s text is a series of recollections about the brief time period between September 1962 and April 1963 that he and Jeanne were acquainted with the Oswalds. A secondary focus consists of a number of meditations on the corrosive effects knowing the Oswalds had on the professional and personal lives of the De Mohrenschildts. "It must be acknowledged that our brief friendship with the Oswalds had strange and adverse effects on our lives." Only in a tertiary sense is the manuscript concerned with Oswald’s guilt or innocence and who the “real criminals” might be. Stating Oswald was a "patsy not involved in any revenge", and referencing articles describing "organized murder for profit", readers are challenged to make up their own minds. This memoir by De Mohrenschildt was edited and annotated as Lee Harvey Oswald As I Knew Him, by Michael A. Rinella. It was released in November 2014 by the University Press of Kansas.
Depictions in the popular media
De Mohrenschildt was played by Willem Oltmans in the 1991 film, JFK and by Bill Bolender in the 1993 TV movie, Fatal Deception: Mrs. Lee Harvey Oswald. He is also mentioned at length in the Stephen King novel, 11/22/63, a time travel novel about the assassination of John F. Kennedy and his Haitian experience in Hans Christoph Buch's novel Haïti Chérie (Suhrkamp, 1990).
De Mohrenschildt was discussed at length in the Tru TV series, Conspiracy Theory with Jesse Ventura. The episode states that George de Mohrenschildt was in fact a CIA handler for Lee Harvey Oswald.
In 1997, Dutch filmmaker Theo van Gogh released the film Willem Oltmans, De Eenmotorige Mug. In the film, journalist Willem Oltmans tells in detail the story of his contacts with De Mohrenschildt (and the mother of Lee Harvey Oswald, Marguerite Oswald) until de Mohrenschildt's death in 1977.
- For example, from the death investigation report by Thomas Neighbors of the Palm Beach County Sheriff's Office:
At 2315 hours, on 29 March 1977, this writer made contact with the victim's wife, MRS. JEANNE de MOHRENSCHILDT, in California… and advised her of her husband's demise; a fact which she had already been made aware of by several newsmen who had telephoned her seeking a story. She stated that she has been married to the victim for the past twenty-one years and noted that over the past several years he has been acting in an "insane manner".
- George H. W. Bush recalled, "I first met De Mohrenschildt in the early 1940s. He was an uncle to my Andover roommate." (The relationship would technically be "step-uncle" as the roommate, Edward G. Hooker, was actually Dimitri von Mohrenschildt's stepson).
