In 1878, Sir William Crookes, a British scientist, displayed the first cathode rays using a modification of the Geissler apparatus. His major contribution to construction of the tube was to develop ways to evacuate almost all the air from the tube. Crookes also carried out many experiments using more reliable equipment to confirm earlier.

Sir William Crookes had set aside part of his home on Mornington Road in London as a private laboratory. Many great events would transpire here, but the first, in 1861, was his observation of a green line in the spectra of certain selenium compounds, an observation that led Crookes to the discovery of the element thallium..

The Discovery of the Electron (William Crookes) The definitive experiments with cathode-ray tubes were done by William Crookes in 1879. Crookes' major contribution was the development of a better vacuum pump that allowed him to produce cathode-ray tubes with a smaller residual gas pressure. Crookes not only confirmed the previous work by.
