William Thomas Green Morton was an American dentist who first publicly demonstrated the use of inhaled ether as a surgical anesthetic in 1846. The promotion of his questionable claim to have been the discoverer of anesthesia became an obsession for the rest of his life. (See link below to his WikiPedia page).
William was born in 1819 in Charlton, Massachusetts to a farmer, James Morton and his wife Rebecca Needham. He studied both dentistry and medicine, but never graduated from either program. In 1844, he married Elizabeth Whitman, niece of former Congressman Lemuel Whitman. They had five children together. Morton died in 1848 from a major stroke.
