1952 
        Donald GLASER invented a bubble chamber. 
        The first bubble chambers were made of Pyrex glass and contained a few 
        cubic centimeters of liquid. 
 1959 
        Nobel Prize for Emilio SEGRE (US) and Owen CHAMBERLAIN (US), for demonstrating 
        the existence of the anti-proton. [more

 1960 
        Nobel prize for Donald A. GLASER (US), for invention of "bubble chamber" 
        to study subatomic particles. [more details]
 1968 
        Nobel prize for Luis Walter ALVAREZ (US)
        He was awarded the 1968 Nobel Prize in Physics for his discovery of a 
        large number of resonance states (subatomic particles that have very short 
        lifetimes and that occur only in high-energy nuclear collisions), which 
        was made possible through his development of the liquid-hydrogen bubble 
        chamber. [more

 1969 
        Nobel prize for Murray GELL-MANN (US), for study of subatomic particles.
        In 1961 GELL-MANN and Israeli physicist Yuval NE'EMAN independently introduced 
        the "eightfold way," or SU(3) symmetry, a table like ordering 
        of all subatomic particles analogous to the ordering of the elements in 
        the periodic table. The 1964 discovery of the omega-minus particle (from 
        a bubble chamber picture), which filled a gap in this ordering, brought 
        the theory wide acceptance and led to GELL-MANN's being awarded the 1969 
        Nobel Prize for Physics. In 1963, GELL-MANN and American physicist George 
        ZWEIG independently postulated the existence of the quark, an even more 
        fundamental elementary particle with a fractional electric charge. Quarks 
        are confined in protons, neutrons, and other particles. [more

        1973 
        Neutral currents were discovered at CERN in 25 ton Gargamelle bubble chamber.

 1974 
        7-foot Brookhaven bubble chamber started to operate. 
        This was the first particle detector of its type in which the chamber 
        through which the particles passed was surrounded by a superconducting 
        magnet. The following year, the 7-foot chamber was used to discover the 
        charmed baryon, a particle composed of three quarks, one of which was 
        the "charmed" quark. This result helped physicists confirm a 
        new member of the quark family.
