Lavoisier has been considered by many scholars to be the “father of chemistry”. Chemists continued to discover new compounds in the 1800s. The science also began to develop a more theoretical foundation. John Dalton (1766-1844) put forth his atomic theory in 1807.

Classical chemistry. His “Elementary Treatise of Chemistry” (1789) was the first modern chemistry textbook.
