DOB: b. April 16 1728 d. December 6 1799 Country of origin: Scotland Discovery: Latent Heat, Specific Heat, Carbon Dioxide Year of Discovery: 1750 Black was a Scottish physicist and chemist. He was the founder of thermo chemistry. In 1750 Black developed the analytical balance which was a beam balanced on a fulcrum. In 1761 black stated that ice was not liquidated by heat but that it absorbed the heat without a rise in temperature. Same thing with boiling. Heat put on water did not mean that the water had to boil, or steam because the water absorbed the heat. That is when the idea of latent heat cam into place. to explain that not everything reacts to heat the same way. he was the cause of the abstract thought of the steam engine. www.britannica.com/EBchecked/topic/67460/**Joseph**-**Black**

Antoine Lavoisier August 26 1743-May 8th 1794 Country of Origin: France Year of Discovery: 1777 Lavoisier was born into a wealthy family and inherited a great fortune at the age of 5 due to his mother’s passing. He grew up in the age of Enlightenment and was able study many new scientific fields because of it. Antoine attended the College Mazarin where he studied chemistry. When he was 28 he married the 13 year old Marie-Anne Pierrette Paulze. At the height of the French Revolution, Lavoisier was accused of selling watered down tobacco and was beheaded for his crimes.

Lavoisier is known for many contributions to the field of chemistry. For instance he is one of the founders of the metric system, he demonstrated the role of oxygen in rusting, and he showed that respiration of oxygen by animals was essentially slow combustion. Among his many scientific discoveries his most notable one is his research on the Law of the Conservation of Mass. This states that matter cannot be created or destroyed. []

Felice Fontana

 DOB: b. April 15 1730 d. March 10 1805 Country of origin: Italy Discovery: Water Gas Shift Reaction Year of Discovery 1780

Fontana was born to an Italian family in Pomarolo. He studied Anatomy and Physiology in the University of Padua. During his life he moved many times. He taught Logic at the University of Pisa, together with the subject of Physics. He was awarded with the task of creating a museum of natural history. During this time his fascination for poisons and iris motions took place. During the years of 1775-1780 he traveled all over Europe doing his research and publishing his experiments. He published a "treaty" opposing theries made about Carbon Dioxide. In order to form carbon dioxide and hydrogen there is a chemical reaction with water called the water gas shift reaction.
