William Crookes
William Crookes was a British scientist in the late 19th and early 20th centuries known for his pioneering work in physics and chemistry. He developed an early type of vacuum tube called the Crookes tube, which emitted rays that led to the discovery of cathode rays—key to understanding electron behavior. Crookes's experiments contributed to our knowledge of atomic structure and radiation, laying groundwork for later discoveries in atomic physics. His work also extended into studying phenomena like phosphorescence and electromagnetic radiation, significantly advancing scientific understanding of atomic and subatomic processes.
