John Dalton (1766–1844) was an English chemist, physicist, and meteorologist best known for his pioneering work in the development of modern atomic theory. He proposed that matter is composed of indivisible atoms and that each element consists of unique atoms with specific weights. Dalton's atomic theory laid the groundwork for our understanding of chemical reactions, particularly the law of multiple proportions, which states that elements can combine in different ratios to form different compounds.
In addition to his contributions to chemistry, Dalton conducted extensive research in meteorology and is known for his studies of color blindness, a condition sometimes referred to as Daltonism in his honor. Dalton was also a prominent figure in the scientific community of his time, and his work has had a lasting impact on various scientific disciplines.
