L.J.M. Daguerre: The History of the Diorama and the Daguerreotype

In 1829, Daguerre partnered with Nicéphore Niépce, an inventor who had produced the world's first heliograph in 1822 and the first permanent camera photograph four years later.[1][2] Niépce died suddenly in 1833, but Daguerre continued experimenting and evolved the process which would subsequently be known as the Daguerreotype. It has recently been discovered that Daguerre may have mislead Niepce's son about the value of the invention in order to better claim any profits from it individually. After efforts to interest private investors proved fruitless, Daguerre went public with his invention in 1839.
