Robert Slatzer, the one who mentioned the Red Diary in a 1974 book, met Marilyn once in 1952 whilst she filmed Niagara. They had a couple of photos together and since her death, he has been a plague to all researchers’ lives. Why?
He insisted he married Marilyn on 4th October 1952 in Mexico. Apparently, they had the wedding certificate burnt as the studio didn’t want them to get married. However, on the date that he states they travelled (3rd) Marilyn is photographed at the Photoplay Awards in Los Angeles. There is also a cheque made out to Jax in Beverly Hills on the 4th October 1952.
He states they were very close until she died despite the fact there are no photos other than those in 1952 or letters.
From Donald Spoto’s book:
While filming scenes at Niagara Falls, [Monroe] was asked by a twenty-five-year-old visitor from Ohio named Robert Slatzer to pose with him for snapshots. For such impromptu photos and importuned autographs, no public figure was ever more generous and cooperative with admirers and strangers than Marilyn, nor was any more exploited before or since her death…
In 1972, with Marilyn conveniently unable to contradict him, Slatzer approached journalist Will Fowler with a short, incomplete article in which Slatzer speculated that Marilyn Monroe’s death was part of a political conspiracy… “Too bad you weren’t married to Monroe,” Fowler said, unimpressed with Slatzer’s proposal. “That would really make a great book.” Soon after, Slatzer contacted Fowler again, saying he had forgotten to mention that he had indeed been married to Marilyn.
“Slatzer made a career of being a pretender,” according to Fowler, “selling gullible talk show producers who don’t do their research very well with the deception that he was married to Marilyn. He was never married to her. He met the star only once, in Niagara Falls… He never met Marilyn before or since.”
Among the most persistent but injudicious of his assertions is his absurd claim that he spent the weekend of October 3 to 6, 1952, with Marilyn Monroe in Tijuana, Mexico, where they were married on October 4… Quite apart from the fact that Marilyn was in Los Angeles that entire weekend, Slatzer could never produce a written record of the union or its dissolution but the receipt from Spoto’s research proves she was in LA. Essentially, he cannot be trusted as a reliable source of information.
The red diary in which he alleges to have existed was meant to have contained many government secrets relating to the Kennedy’s. This is a falsehood that he made in 1974. He said Marilyn was going to reveal these secrets to the world if RFK ended their romance. According to Slatzer Marilyn also had recorded conversations with the president and attorney general. Only Slatzer knew about this. But according to him, therefore the Kennedys had Marilyn murdered. The only red book that matches this description was a collection of Arthur Miller’s works that he got made and dedicated to Marilyn.
