What did Johann Becher discovered?

Answer 1

Johann Becher was a 17th-century German alchemist and chemist known for his work on the nature of matter. He proposed the concept of "phlogiston," a substance he believed was released during combustion, which was a precursor to later theories of combustion and oxidation. Becher's ideas contributed to the development of early chemistry, laying groundwork for future scientists like Antoine Lavoisier, who later debunked the phlogiston theory. His influential writings helped shape the transition from alchemy to modern chemistry.
