Why did Robert boyle discover hydrogen?

Robert Boyle did not discover hydrogen; rather, he was instrumental in the study of gases and contributed to the development of modern chemistry through his experiments and the formulation of Boyle's Law. Hydrogen was first recognized as a distinct substance by Henry Cavendish in 1766, who identified it as a flammable gas produced from the reaction of acids with metals. Boyle's work laid the groundwork for later scientists to explore gases, including hydrogen, and understand their properties.
