Johann Heinrich Schulze (1687-1744) was a German professor of anatomy and the physical sciences, with extensive knowledge in medicine and chemistry. His 1727 discovery that silver salts darken in the presence of light provided the foundation for the photographic process. At the turn of the nineteenth century, Thomas Wedgwood and Sir Humphry Davy built upon his discovery to make cameraless images, and shortly after, Joseph Nicéphore Niépce, added a camera and lens to capture and hold images from life.
