1875 – Crookes’ tube

1875 – Crookes’ tube

English physicist William Crookes expanded on the vacuum tube research done by Geissler, Plucker and Hittorf and created a tube with a greater vacuum that became the new standard. In 1876 Eugen Goldstein called the display inside the tube, “cathode rays” and the tubes became known as cathode ray tubes, which was eventually abbreviated to CRT.
