Oxyhydrogen blow-pipe

In 1801, Robert Hare (1781-1858) presented to the Chemical Society of Philadelphia his paper, Memoir of the Supply and Application of the Blow-Pipe. It presented the twenty-year-old scientist's discovery relating to the intense production of heat with his oxyhydrogen blow-pipe, progenitor of the welding torch. The Society published the paper the following year, and accounts of the invention also appeared in Tilloch's Philosophical Magazine and in the Annales de Chemie. In 1839 the American Academy of Arts and Sciences awarded him the first of its Rumford Medals.
