Camera's have been used for centuries as a way of documenting people's lives. The very first "camera" known to history was called the Camera Obscura (or the Pinhole Camera) - this is believed to date back to the ancient Greeks and ancient Chinese. In the early times of this particular camera it was used to watch solar eclipses. It wasn't until 1827 that Joseph Nicephore Niepce was able to use the Camera Obscura to preserve images in photographic forms - these early photos were known as heliographs (or Sun Prints). As time evolved people discovered ways of creating more permanent photos and photo taking devices, like the ones we have today!
