Patent for Pyréolophore

Date: July 20, 1807 • Location: Paris, France

French brothers Claude and Nicéphore Niépce received a patent for their Pyréolophore, one of the world's first internal combustion engines.

Claude Félix Abel Niépce was a French inventor and the older brother of the more celebrated Nicéphore Niépce. Claude traveled to England to try to find a sponsor for their internal combustion engine and died there. His brother's later successful development of photography has eclipsed the part played by Claude.
