Willem Oltmans was an investigative reporter for Dutch TV in the Netherlands. During World War II he was part of the Dutch resistance where he did such things as blow up trains. In the fifties he wrote articles critical of the government and the they tried to keep him from getting any work. Courts ruled the government acted improperly and they had to pay him for their actions.

During the sixties, he was working for Dutch broadcaster NOS covering the United States. He interviewed Margarite Oswald in 1964. His 1967 interview with George de Mohrenschildt created a 40 minute film which disappeared from NOS in 1977.

That same year Oltmans again interviewed de Mohrenschild shortly before his death. He said that there was a recording in the house that picked up footsteps of someone before the blast of the shotgun and then footsteps leaving.

After these events Oltmans continues his globe trotting reporting, and later, played the part of George de Mohrenschildt in the JFK film.

Reporting on the Kennedy Assassination
by Willem L. Oltmans


In March 1964 the Dutch journalist Willem Oltmans (1925–2004) encountered Marguerite Oswald, Lee Harvey Oswald’s mother, at JFK International Airport. In April 1977, he found himself testifying before the House Select Committee on Assassinations (HSCA). In the thirteen years between these two events, Oltmans conducted his own investigation into the assassination of John F. Kennedy—an undertaking that would bring him into contact with a host of individuals with prominent roles in the case, most notably George de Mohrenschildt (1911–1977), whose involvement with Oswald and whose own untimely death remain mysteries to this day.

Reporting on the Kennedy Assassination is Oltmans’s account of his investigation, published here for the first time in English. Combining personal memoir and factual reporting, the book chronicles the journalist’s interviews with figures such as Jim Garrison and Cyril Wecht, his long and complicated friendship with de Mohrenschildt and his wife, and his own whirlwind experience in the media spotlight. Most saliently, Reporting on the Kennedy Assassination offers an intimate look at Oltmans’s collaboration with de Mohrenschildt on the book that would later become Lee Harvey Oswald as I Knew Him, and at the circumstances surrounding de Mohrenschildt’s death and his possible implication in Oswald’s actions.

Systematically annotated and fact-checked, with an insightful introduction from editor Michael Rinella and a wealth of rare photographs and letters, this book provides a fascinating portrait of one of the twentieth century’s most controversial journalists even as it completes a critical chapter in the investigation of the Kennedy assassination.
