Discovered the electron and proposed the first model of the atom.

"As the cathode rays carry a charge of negative electricity, are deflected by an electrostatic force as if they were negatively electrified, and are acted on by a magnetic force in just the way in which this force would act on a negatively electrified body moving along the path of these rays, I can see no escape from the conclusion that they are charges of negative electricity carried by particles of matter."

— from Cathode Rays, 1897

"We have, in the cathode rays, matter in a new state, a state in which the subdivision of matter is carried very much further than in the ordinary gaseous state: a state in which all matter—that is, matter derived from different sources such as hydrogen, oxygen, etc.—is of one and the same kind; this matter being the substance from which all the chemical elements are built up."

Cathode Rays Lecture 1897

I am ever more convinced that the physician who knows nothing of the X-rays will soon be as much out of date as is the chemist who ignores the periodic table.

Speech 1896

The discovery of the electron has given us a new conception of the structure of matter.

Book: Electricity and Matter 1904

In all cases where the discharge passes through a gas at low pressure, the negative electrode is the source of the rays.

Scientific Paper 1897

The rays from the cathode are not due to a special kind of light, but to a stream of material particles.
