Pauline began as a "subject" of hypnotists Herbert Flint and The Great McEwen.
When he thought he was ready in 1910, he went to New York and engaged
the services of Percy Williams, a widely known vaudeville director.
Almost overnight, Pauline was lifted to the status of stardom becoming one of
the highest paid performers in vaudeville.
In 1911, he played under the title "De Pauline," which was used intermittently throughout his career.
By the end of 1912, he was in London playing the Palladium Theatre.
After about a year in Europe, Pauline returned to the United States billing
himself as "Prof. De Pauline, the French Hypnotist."
Other billings over the years included "The Eminent French Scientist",
"The Eminent French Psychologist" and "Prince of Fun-Makers",
"The World's Greatest Psychologist and hypnotist" and "Dr. J. Robert Pauline".
In 1920, he acted in The Mystery Mind, a 15-part movie serial written by Arthur B. Reeve, famous author of
the Craig Kennedy, Detective mysteries, and John W. Grey. It was his only film role.
In 1925, Pauline's career was almost ended when he was convicted and sentenced to jail
for throwing a waiter off the ninth floor of a New York hotel.
He returned to performing in late 1926 and by 1928 he had worked his way back as a headliner.
Pauline's career gradually slowed down and he retired to
West Sparta, New York in 1938, four years before his death of a heart attack.
