Off course. He discovered the proton with the help of discharge tube with a perforated Cathode. Some positively charge particles were detected behind perforated cathode. these particles were of different mass and charge for different gases used in the tube (i.e. had different m/e). the lightest particles were formed when hydrogen gas was used. So the word proton was give so, because these particles for hydrogen were the lightest and came on first in order of mass. (Greek 'Protos'= First)
