1725 (circa) � Johann Heinrich Schulze makes fleeting "photographs" of words by using stencils, sunlight, and a bottled solution of chalk and silver nitrate, simply as an interesting way to demonstrate that the mixture inside the bottle darkens where it is exposed to light.
1800 (circa) � Thomas Wedgwood conceives of making permanent pictures of camera images by using a durable surface coated with a light-sensitive chemical. He succeeds only in producing silhouettes and other shadow images, and is unable to make them permanent.
1816 � Nic�phore Ni�pce succeeds in making negative photographs of camera images on paper coated with silver chloride, but cannot adequately "fix" them to stop them from darkening all over when exposed to light for viewing.
