Dear Amy: Who invented the camera? — Stacy, Oklahoma City

Dear Stacy: In 1826 a Frenchman named Joseph Nicéphore Niepce made the first permanent photograph using a sliding wooden box. This may have been the first photo taken, but the camera itself dates back much further.

During the 11th century, lenses were created to project an object of interest onto a viewing surface, but there was no way to preserve these images apart from drawing them.

In 1685, Johann Zahn invented the first portable camera. Louis Daguerre followed up with a practical photographic method called the daguerreotype in 1835. Later, in 1888, George Eastman invented photographic film and gave birth to the popular Kodak cameras.

Digital cameras became a huge hit in 1990s and are still evolving today. Even cell phones can take pictures to conveniently document memories. For more details, visit www.factmonster.com/
