A brilliant, quarrelalous American polymath who claimed credit for the telegraph and anesthesia, only to see both discoveries become subjects of bitter, lifelong controversy.
Charles Thomas Jackson was a man who stood at the precipice of epochal discoveries but could never quite claim them as his own. A Harvard-trained physician and gifted geologist, his mind was a whirlwind of ideas across chemistry, mineralogy, and early electromagnetism. In 1832, on a ship returning from Europe, he described to a fellow passenger, Samuel Morse, the concept of an electric telegraph. Morse would patent it and get the fame. A decade later, after experimenting with ether's effects, he suggested to a dentist, William Morton, that it could be used for painless tooth extraction. Morton demonstrated surgical anesthesia at Massachusetts General Hospital, igniting another fame-and-fortune battle. Jackson spent the rest of his life embroiled in vicious priority disputes over these inventions, lawsuits that drained him and tarnished his reputation. He conducted the first state geological survey of Maine and was an early analyst of the mineral resources of the Lake Superior region, but these solid achievements were overshadowed by the controversies. His final years were marked by mental illness and institutionalization, a tragic end for a scientist of immense, if contentious, vision.

He was on the same transatlantic voyage as Samuel Morse in 1832 and later claimed he gave Morse the core idea for the single-wire telegraph.
The bitter 'Ether Controversy' involved multiple lawsuits and even a Congressional inquiry to determine the true discoverer of anesthesia.
He was a close friend and early mentor to poet Oliver Wendell Holmes Sr., who actually coined the term 'anesthesia.'
“The idea was clear in my mind before it was in his hands.”
