Strange quark
The first strange particle (a particle containing a strange quark) was discovered in 1947 (kaons), but the existence of the strange quark itself (and that of the up and down quarks) was only postulated in 1964 by Murray Gell-Mann and George Zweig to explain the Eightfold Way classification scheme of hadrons. The first evidence for the existence of quarks came in 1968, in deep inelastic scattering experiments at the Stanford Linear Accelerator Center. These experiments confirmed the existence of up and down quarks, and by extension, strange quarks, as they were required to explain the Eightfold Way.
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.
