Georg Stahl, Joseph Priestley, Antoine lavoisier
Georg Stahl
Georg Ernst Stahl was a German chemist, physician and philosopher. he was born on October. 21, 1660, in Ansbach, Franconia Germany and died on May 14, 1734, in Berlin, Prussia.his work on phlogiston were accepted as an explanation for chemical processes.
His discovery was a major discovery in chemical theory and made it easier for scientists in the near future. This led to the realisation that phlogiston wasn't what left the substances when burned, but instead the left electrons.
Georg's theory was that when things are burned the phlogiston leaves the substance and rises which is visible through smoke or fire, the less residue the more phlogiston. The flaw in Georg Stahl’s theory was that metals increase in mass when burned, to solve this phlogiston was classed as a negative mass.

Joseph Priestley
Joseph Priestley was an 18th-century English theologian, Dissenting clergyman, natural philosopher, chemist, educator, and Liberal political theorist who published over 150 works.He was borne on March 13, 1733, in Birstall Fieldhead, Yorkshire , England and died on February 6, 1804, in Northumberland, Pennsylvania, U.S.
Joseph Priestly discovered that there were all different types of airs which today known as gasses. Priestly was able to record eight different types of gasses including oxygen which he called "dephlogisticated air" in 1774.After he died a award in his honour was made, the Priestly Medal is the highest award given by to an American chemist by the Society.

Antoine Lavoisier
Antoine-Laurent de Lavoisier was a French nobleman and chemist.He was very important to the 18th-century chemical revolution and had a large influence on both the history of chemistry and the history of biology.He was born on August 26, 1743,in Paris, France and died on May 8, 1794, in Paris, France.
Lavoisier’s theories were based off Stahl’s and Priestly’s theories. However though Lavoisier discoveries are much more recognised in modern science.
Using his wealth he would challenge the theories of Georg Stahl and Joseph Priestly.Antoine Lavoisier is most known for his discovery of the role oxygen plays in combustion. He recognised and named oxygen and hydrogen and opposed the phlogiston theory.He helped construct the metric system, wrote the first extensive list of elements, and helped to reform chemical nomenclature. Lavoisier created the “Law of Conservation of Mass”, this law states that matter cannot be destroyed or created. He also concluded that element is a substance hat cannot be broken down any further.
