-Antoine-Laurent+Lavoisier

Antoine-Laurent Lavoisier In France in the 1700s, Lavoisier worked on advancing the science of chemistry. He helped transform chemistry from a science of observation to the science of measurement. Lavoisier designed a balance that could measure mass to the nearest 0.0005 gram. He settled a long debate about how materials burn. He knew that there were two main gases in the air- nitrogen and oxygen. Lavoisier was able to show that oxygen was needed in order for things to burn. His wife, Marie Anne, helped him with his scientific work. Lavoisier worked during the time of the French Revolution. He financed his own work and was a member of the despised royal taxation commission. He was targeted by the people because he was part of the association and was arrested, tried, and beheaded in 1794.
