Quark
The quark model was independently proposed by physicists Murray Gell-Mann and George Zweig in 1964. Quarks were introduced as parts of an ordering scheme for hadrons, and there was little evidence for their physical existence until deep inelastic scattering experiments at the Stanford Linear Accelerator Center in 1968. Accelerator experiments have provided evidence for all six flavors. The top quark, first observed at Fermilab in 1995, was the last to be discovered.
Daniela Bortoletto
Bortoletto moved to Purdue University to pursue a postdoctoral fellowship. In 1994, she received a NSF Career Advancement Award and became the Alfred P. Sloan Research Fellow. While part of the CDF collaboration in 1995, she co-discovered the top quark. Two years later, she won a NSF Faculty Early Career Development Award. In 2004, she gained fellowship of the American Physical Society.
