Through Cannon, Ether and Mediumship

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.
