ANGELO SALA
(1576 - 1637)
Self-educated chemist that experimented with silver salts. In 1614 published that the paper containing silver nitrate reacted with sunlight causing it to darken. Same observations were made by Robert Boyle, who unfortunately gave the wrong explanation by stating that the above reaction occurred due to air and not by sunlight.
