Crookes, Sir William

Sir William Crookes was a British scientist known for his work in physics and chemistry during the late 19th and early 20th centuries. He invented the Crookes tube, an early type of vacuum tube that produced cathode rays, which later contributed to the discovery of electrons. Crookes conducted experiments with these rays, advancing understanding of atomic structure and electromagnetism. His research laid groundwork for the development of technologies like television and electron microscopes. Overall, Crookes was a pioneering figure in exploring the properties of vacuum and light, significantly impacting modern physics and electronics.
