Father of Chemistry is Antoine Lavoisier, a French scientist whose work revolutionized the study of matter and chemical reactions. He introduced a systematic approach to experiments, named and classified chemical substances, and helped establish the law of conservation of mass. 

Lavoisier’s discoveries changed chemistry from a mystical art into a true science, making him one of the most influential figures in scientific history.

Who is the Father of Chemistry?

Antoine Lavoisier is widely regarded as the Father of Modern Chemistry. Born in 1743 in France, Lavoisier introduced a new level of accuracy and organization to chemical research. He defined elements, named key gases like oxygen and hydrogen, and established the Law of Conservation of Mass proving that matter is neither created nor destroyed in a chemical reaction.

Before Lavoisier’s time, people believed in the phlogiston theory, which wrongly explained combustion. Through his precise experiments, Lavoisier disproved that theory and demonstrated that oxygen plays a vital role in burning and respiration. His groundbreaking textbook, Traité Élémentaire de Chimie (Elementary Treatise of Chemistry), published in 1789, is considered the first modern chemistry textbook.

Antoine Lavoisier Key Contributions

Antoine Lavoisier played a crucial role in shaping modern chemical science. His discoveries and systematic methods brought accuracy, organization, and logic to the study of chemistry. Below are his most important contributions:

1. Law of Conservation of Mass
   Lavoisier proved that matter is neither created nor destroyed in a chemical reaction. The total mass of the products always equals the total mass of the reactants. This discovery became one of the fundamental laws of chemistry.
   
2. Discovery of Oxygen’s Role
   He identified oxygen’s essential part in combustion and respiration, disproving the old phlogiston theory. His experiments showed that burning is a reaction involving oxygen.
   
3. Modern Chemical Nomenclature
   Lavoisier helped develop a clear and consistent system for naming chemical elements and compounds. Many names he introduced, such as oxygen, hydrogen, and sulfur, are still used today.
   
4. Accurate Measurement and Experimentation
   He emphasized precision in experiments, using accurate instruments to measure temperature, pressure, and mass. This practice set new scientific standards and established chemistry as a quantitative science.
   
5. First Modern Chemistry Textbook
   Lavoisier’s book, Traité Élémentaire de Chimie (Elementary Treatise of Chemistry), published in 1789, is regarded as the first modern chemistry textbook. It organized chemical knowledge clearly and introduced many of the principles still taught today.
   
6. Definition of Elements and Compounds
   He defined elements as substances that cannot be broken down by chemical means and classified compounds based on their composition, helping scientists better understand matter.

Father of Chemistry in India: Prafulla Chandra Ray

Just as Lavoisier shaped global chemistry, Prafulla Chandra Ray is known as the father of chemistry in India. He was a respected Bengali chemist and educator who made a significant impact on science and industry in the country.
