Explanation:

Eugen Goldstein (1886)

First to observe the proton (then unnamed).

During his work with discharge tubes, he observed rays traveling from cathode to anode (electrons) and also noticed the presence of waves traveling in the opposite direction.

He also contributed greatly to the study of cathode rays; in 1876 he showed that these rays could cast sharp shadows, and that they were emitted perpendicular to the cathode surface
