In 1886 Eugen Goldstein discovered canal rays (also known as
anode rays) and showed that they were positively charged
particles (ions) produced from gases. Menas,originally
Goldstein postulated that there were some positively charged
particles... but he didn't say that they were Protons!!

Following the discovery of the atomic nucleus by Ernest
Rutherford in 1911. This was confirmed experimentally by
Henry Moseley in 1913 using X-ray spectra. In 1919
Rutherford proved that the hydrogen nucleus is present in
other nuclei, a result usually described as the discovery of
the proton.
