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.
Quink
A popular misconception is that the ink was invented by a Filipino, Francisco Quisumbing, and takes its name from 'Quisumbing Ink'. Although this apocryphal tale appears on numerous websites, no is ever cited. The accounts uniformly identify the supposed inventor as 
Francisco Quisumbing, a Filipino botanist who studied in both the Philippines and the US, gaining a PhD in Plant Taxonomy, Systematics and Morphology from the University of Chicago in 1923. What biographical information that can be found is incomplete and unreliable. There is no indication that such a person ever worked for Parker.
