John Dalton was the first to formally theorize the atomic theory of matter in the early 19th century. He proposed that all matter is composed of tiny, indivisible particles called atoms, which combine in specific ratios to form compounds. Dalton's theory laid the groundwork for modern chemistry by introducing concepts such as atomic weight and the idea that chemical reactions involve the rearrangement of these atoms.
