<Owen Chamberlain> helped establish the <antiproton> by distinguishing a rare massive negative particle from an intense background of lighter particles. Magnetic analysis fixed <momentum>, while time-of-flight and <Cherenkov radiation> measurements constrained <speed>. Together these quantities tested whether the inferred <mass> matched that of the <proton>. His lecture emphasizes both the apparatus and the inference drawn from the particle's existence, separating discovery from later studies of its interactions.<The early antiproton work by Owen Chamberlain>[1959 lecture, magnetic selection, velocity measurements and antiproton identification]{ref}
