Frenchman Joseph Nicéphore Niépce took the first lasting photograph in 1826 or 1827 through a process he termed heliography. Niépce took earlier exposures, but they turned out to be negatives and lost their image in light.
Niépce and his brother Claude considered the potential for photographs around 1793, but their work on internal combustion engines kept the two busy. Decades later at his family home, Le Gras, Niépce experimented with different heliograph techniques. His first lasting image capture was of the street-side view from an upstairs' window. The exposure lasted between eight hours and two days. He partnered with Louis-Jacques-Mandé Daguerre from 1829 until his death in 1833. Daguerre later invented the daguerreotype print, which was crisper, more detailed and faster than Niépce's heliography.
