Henry Jacob Bigelow Inhaled Nitrous Oxide While an Undergraduate at Harvard College.

When teenaged Henry Jacob Bigelow was an undergraduate at Harvard College in 1833-1837, he prepared nitrous oxide gas for demonstrations to other students. Bigelow's son, William Sturgis Bigelow, related the claim, and there is an eyewitness account from Augustus Goddard Peabody, a fellow Harvard undergraduate with Bigelow. Peabody wrote to Henry David Thoreau about a nitrous frolic. College chemistry primed Bigelow to support the concept of inhaled surgical anesthesia when the idea came to Boston in 1845-1846. Bigelow's chemistry professor was John White Webster. According to Harvard alumnus Edward Everett Hale, in addition to demonstrating effects of nitrous oxide, Webster presciently treated two cases of carbon monoxide poisoning with copious volumes of synthetic oxygen gas. The career of Webster was inhibited by financial difficulties that were suspected to be contributory when he was convicted of the 1849 murder of physician George Parkman at the Harvard Medical School, then adjacent to Massachusetts General Hospital and its Ether Dome. Webster suffered the death penalty in 1850.
