Hans Holzer's "Window to the Past: Exploring History Through ESP"

Here's another in an occasional series about the more obscure paperbacks penned by parapsychologist and ghost hunter Hans Holzer. The most recent post before this looked at Charismatics.

• Title: Window to the Past: Exploring History Through ESP
• Additional cover text: Psychic "conversations" with some of the great figures of the past (at least they put "conversations" in quotation marks)
• Author: Hans Holzer (1920-2009)
• Cover designer: Unknown

• Interior illustrations: Catherine Buxhoeveden (born 1939). Holzer and Buxhoeveden were married in 1962 and later divorced. She provided illustrations for several of his books, including this one. (One of her illustrations is below.) The Internet Speculative Fiction Database states: "A sixth generation descendant of Catherine the Great, Countess Catherine Geneviève Buxhoeveden's family were Russian royalty in exile, living in France until the beginning of World War II, when they settled in Italy (1935). Catherine was born shortly thereafter in Castle Rovina. ... Catherine, sometimes referred to as 'The Haunted Countess,' believed that the castle in which she was born had been haunted." Alexandra Holzer, the daughter of Hans and Catherine, penned the 2008 book Growing Up Haunted: A Ghostly Memoir.
• Questions posed on the back cover: Who really planned Lincoln's murder, carried out by John Wilkes Booth? ... Where did the Vikings land in America 500 years before Columbus? ... Did Camelot really exist? ... What is the truth behind the Mayerling tragedy? ... Was Aaron Burr really the villain history has made him out to be? ... Why was Nell Gwyn dropped by her royal lover Charles II?

• First sentences:  "Goodness," Ethel Johnson Meyers said, and looked at me with a big frown that turned matriarchal face into a question mark, "What on earth is that fat fellow doing with all those dancing girls in harem costumes?" Ethel wasn't watching the Late Late Show. She was holding a cigarette case I had handed her for the purpose of psychometrizing it."
• Last sentence: It is as if we are privileged to be present at the events themselves, catapulted back in time, eavesdropping and observing without being seen, but recording for our time that which is of another time.
• Random excerpt #1: If Edwin Booth came through Sybil Leek to tell us what he knew of his brother's involvement in Lincoln's death, perhaps he did so because John Wilkes never got around to clear his name himself.
• Random excerpt #2: All this correspondence came to a sudden climax when Johnstone informed me that new digs were going on at what might or might not be the true site of Camelot.
• Random excerpt #3: I thanked Alice and decided to hold another investigation at the site of Café Bizarre¹, since the restless spirit of the late Vice-President of the United States had evidently decided to be heard once more.

• Rating on Amazon: 4.8 stars (out of 5) 
• Amazon review excerpt: In 2019, J.H. Clemson wrote, "My grandfather was with Hans Holzer and Sybil Leek on the Constellation in Baltimore. My grandfather was involved in the restoration of the ship as part of the Maryland Naval Militia and was invited along. He attested to all that went on! So I can say that at least that part of the book is accurate!"

Footnote

1. According to Rock & Roll Roadmaps, Café Bizarre in Greenwich Village was the club were Andy Warhol discovered The Velvet Underground; Warhol soon became their manager. And, according to a 2013 comment on Rock & Roll Roadmaps, the site of Café Bizarre was said to be "the former stable of Aaron Burr, who shot Alexander Hamilton in a duel. Still the wodden [sic] loft which looked very much like the hayloft of a barn." Café Bizarre as razed around 1984 and the site is now part of the NYU's law school dormitories.
