ALEXANDER
THE MAN WHO KNOWS
This exclusive series explores the fascinating lives of mentalism's trailblazers—artists who turned psychological illusion into a global spectacle. And we begin with perhaps the most legendary and controversial figure of them all: Claude Alexander Conlin, better known as Alexander: The Man Who Knows.

ALEXANDER
THE MAN WHO KNOWS(1880 – 1954)
A Man Surrounded by Mystery, Fame, and Scandal
Alexander's story reads like a Hollywood script, filled with innovation, deception, ambition, and intrigue. Born on 30 June 1880 in the small town of Alexandria, Dakota Territory (now South Dakota), to Irish immigrant parents, he would become one of the most financially successful and influential mind readers in history.
Although he started as a mediocre magician, often borrowing tricks from others (including Houdini's famous escape acts), he eventually stumbled into greatness and immense wealth as a mind reader. Alexander's profound grasp of human psychology, unmatched marketing genius, and daring willingness to borrow, adapt, or outright steal ideas to refine his act. He was, in short, an entrepreneurial showman who knew how to sell mystery to a curious and captivated public.

A Tumultuous Start and a Fateful Detour into Spiritualism
Claude was raised in southeast Alaska, one of several siblings, including his brother Clarence ("CB"), who also explored mentalism—though he never reached Claude’s later fame. As a young boy, Claude loved hunting, fishing, and reading voraciously. He spent hours at the local library, especially drawn to magic books like Hoffmann’s Modern Magic. He also found creative inspiration in the anatomical illustrations from his father’s medical textbooks.
A Rebellious Turn and a Chance Encounter
At 17, Claude was expelled from school. Instead of following his parents’ wishes, he headed east—and by chance, found himself working at the spiritualist resort of Lily Dale near Cassadaga, New York. It was there that he studied the deceptive methods used by fraudulent mediums. He quickly mastered billet switches, sleight-of-hand tricks, and the art of psychological misdirection—skills that would become central to his future as a mentalist.
Gold Rush, Friendship, and Legend
On his journey back west, Claude reportedly met famed magician T. Nelson Downs, known as “The King of Koins.” Later, he travelled north to Alaska to chase fortune during the Gold Rush. During this period, he formed a lasting friendship with Greek immigrant Alexander Pantages, who would later become a vaudeville magnate. One final twist in Claude’s early story: he was rumoured to have shot the infamous gangster Jefferson “Soapy” Smith. While this tale added to his mystique, it was likely a clever invention—part of the legend-building that would surround his career for years to come.
Becoming "Alexander the Great"—Then "The Man Who Knows
The First Steps onto the Stage
Claude’s stage career began in 1898, at the age of 18. Just a few years later, in 1902, he rebranded himself as “Alexander the Great” and joined Seattle’s bustling vaudeville circuit, performing illusions and escape acts. Much of his early material imitated Houdini, as he tried to compete in the booming world of escapology.
A Tumultuous Personal Life
Behind the scenes, his personal life was just as dramatic. He married Jessie Cullen in 1902, though the marriage ended within a year. Not long after, he began a controversial relationship with Ethel Lyman—whom he had met when she was only 14—a detail that stirred gossip even at the time.
The Blizzard That Changed Everything
Everything shifted one snowy night. Due to severe weather delays, his props were stranded, leaving him unable to perform his planned illusions. Forced to improvise, Claude turned to a short, "propless" mind-reading routine. To his surprise, it captivated the audience and received a thunderous response.
From that moment on, he embraced a new direction.
Reinvention as “The Man Who Knows”
Soon after, he rebranded once again—this time as “Alexander the Man Who Knows.” Adopting Oriental robes and a bejewelled turban, he crafted a mysterious, Eastern persona that enhanced the theatrical nature of his performance. Audiences were astonished by his apparent psychic abilities, convinced he truly knew their deepest secrets.
It was stagecraft, yes—but it was also genius. And it worked.
Stagecraft, Technology, and the Birth of Modern Mentalism
Alexander pioneered concealed electronic devices at the peak of his fame decades ahead of his time. He ran wires under stages, used earpieces hidden in his turban, and even installed listening devices in theatre toilets to gather intelligence on audience members. His ability to "read minds" was a sophisticated blend of espionage, psychological suggestion, and technological trickery.
He was also a skilled magician, incorporating classic stage effects into his act, including the Nest of Boxes, Spirit Painting, and the Asrah levitation. These illusions added variety and visual interest, keeping his mental act from becoming repetitive.
One of his most lucrative innovations? Selling mystical merchandise. Alexander established a mail-order empire, peddling books, crystal balls, charms, and spiritual guides, all supported by six full-time employees.


Marketing Masterclass: Posters, Personas, and Profits
Alexander understood branding in a way few magicians of his era did. His posters remain iconic, featuring bold typography and mystical symbols, and he even invented Eastern scripts to enhance their exotic feel. He knew how to create buzz and mystique, often giving himself a darker skin tone in illustrations to appear more "Eastern."
At one point, he promoted himself under a different persona, "Astro the Seer", to distance his psychic readings from his stage identity. He charged clients handsomely for private consultations, raking in even more revenue than box office sales.
Publishing and the Dr. Q Mysteries
In his 40s, Alexander started publishing, creating his C. Alexander Publishing Company label. His most famous work, The Life and Mysteries of the Celebrated Dr. Q, remains a classic of mentalism literature. He also produced a series called The Inner Secrets of Psychology and distributed private materials to followers of his Crystal Silence League.
He was reportedly not above sending assistants to steal pages from library psychology texts; content was then plagiarised and rebranded as his wisdom.
At the end of each show, he'd often proclaim, "Someday, psychology will be taught in schools!" This statement drew laughs then but now seems oddly prophetic.
A Life of Excess: Love, Crime, and Legacy
Alexander's personal life was as flamboyant as his career. By some accounts, he had up to 12 marriages, including instances of bigamy and multiple simultaneous wives. His third wife, Della Martell, was just 17 when they married in 1907. His fourth, Lillian Marion, became a key figure in his act and remained with him for 14 years.
The list of alleged crimes linked to Alexander reads like a criminal dossier: fraud, money laundering, adultery, drug smuggling, and grand larceny. The FBI reportedly kept a file on him.
Despite this, his show remained a huge success, selling in theatres across the U.S. and Canada. He also made over $4 million (roughly £150–200 million in today's money) before retiring in 1924, aged just 43.
He spent his final decades in leisure, hunting, fishing, and photographing nude women, which he sold to calendar companies for an extra $40,000. He died in 1954, aged 74, leaving behind a legacy that shaped the very art of mentalism.

Legacy and Influence
Today, Alexander is regarded as a foundational figure in the world of psychological illusion. His techniques and persona influenced generations of mentalists, including many modern performers. His flair for theatricality, mastery of psychology, and pioneering use of technology laid the groundwork for acts like Derren Brown.
