Lavoisier was born in 1743 and was one of the most influential chemists of his time. He proved his own Lavoisier's Oxygen Theory when he decomposed water into hydrogen and oxygen gases. although this had already been done he was able to prove the conservation of matter theory. He published his own chemistry textbook in 1789 in which he named a total of 33 chemical elements. He was an important part of the French Revolution and was appointed Secretary of the Treasury in 1791. He helped establish the metric system. In 1794 Lavoisier was guillotined for conspiracy against the people of France.

Born in 1736, Coulomb was a French physicist best known for the formulation of Coulomb's law, which states that the force between two electrical charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. Coulombic force is one of the principal forces involved in atomic reactions. He died in 1806.

[] Coulomb's torsin balance could measure electrostatic force.

Joseph Black was born in 1799. He was a Scottish physician and chemist. He discovered latent heat, specific heat, and carbon dioxide. In 1750, Black invented the analytical balance which was far more accurate than all other balances of the day and is still used in chemistry labs to this day. His discovery of latent heat is what he is most remembered for because this discovery had a profound effect on the chemistry world and led to such innovations as the steam engine. He died in 1799.
