Modern Chemistry Robert Boyle Joseph Priestley First person to use scientific method in chemistry. Determined difference between mixtures and compounds. Developed Boyle’s Law Joseph Priestley Identified chemical substances Researched “airs” – ex. Nitrous Oxide, Ammonia, and Oxygen

Medical Advances Paracelsus – Swiss doctor Anton van Leeuwenhoek specific diseases had specific external causes – mostly from poisons. Anton van Leeuwenhoek explored tiny organisms through a microscope. He opened the door for the discovery of germ-caused diseases.
