John Dalton (1766–1844) was an English chemist, meteorologist, and physicist, best known for his pioneering work in the development of modern atomic theory. In 1803, Dalton proposed that all matter is composed of indivisible particles called atoms, each with its own unique properties. He suggested that atoms of different elements vary in size, mass, and properties and that chemical reactions involve the rearrangement of these atoms without their creation or destruction. Dalton’s atomic theory provided a conceptual framework for understanding chemical reactions and laid the foundation for the field of modern chemistry. Additionally, he introduced the concept of partial pressures in gases, known as Dalton’s law, and made significant contributions to meteorology, particularly in the study of color blindness. Dalton’s work has had a profound and lasting impact on the fields of chemistry, physics, and materials science.
