Robert Hanham Collyer
British phrenologist, mesmerist, lecturer, author, and amateur inventor
Robert Hanham Collyer (1814 – c. 1891) was a British physician, phrenologist, mesmerist, lecturer, author, and inventor mostly active on the east coast of America and Canada during the 19th-century.
Collyer was known for his showmanship and became a popular traveling lecturer. In 1839, he discovered, conceived, and promoted the practice of "phreno-magnetism", but relinquished his claims as mistaken by mid-1843.
He was also involved in a number of scandals and rivalries, including a claim that he originated inhalation anesthesia for surgery before William T. G. Morton, who is generally credited with the discovery.
Early life
Robert Hanham Collyer was born in St Helier, Jersey to Ann Du Jardin (1796-1879), and Robert Mitchell Collyer (1787-1859), although details of his early life are hazy.
Phrenology
He studied phrenology under Johann Gaspar Spurzheim in Paris; and, then, attended classes at London University, where he studied medicine with John Elliotson — the founder and first President of the London Phrenological Society, and an early advocate of mesmerism in England (and, later, joint editor of The Zoist: A Journal of Cerebral Physiology & Mesmerism, and Their Applications to Human Welfare) — for at least two years, but did not go on to graduate.
In March 1836, aged 22, he and his parents and siblings migrated to America, where he traveled along the east coast of the United States and Canada giving lectures on phrenology. In-between lecturing he received the standard "quickie" degree from Berkshire Medical College. After receiving his degree, and having been mesmerized by Dr T. Cleaveland in October 1839, Collyer became more and more interested in mesmerism, and added mesmeric demonstrations to his lecture circuit.
Phreno-magnetism
He also began serving as editor of Mesmeric Magazine; and, in 1839, he discovered, and began to develop what he called "phreno-magnetism"; a practice which aimed to activate specific "phrenological organs" through mesmeric influence, or animal magnetism.

Why this record matters
The phrase “british phrenologist, mesmerist, lecturer, author, and amateur inventor” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Jun 16, 2026. The linked authority identifier is Q124098382. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1814, 1891, 1839 and 1843.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
