Filipino Chemist - Francisco Quisumbing

The invention of the Quink form of pen ink is credited to the Filipino chemist, Francisco Quisumbing. This unique form of ink is quick drying, with a special cleaning property that manages to keep the pen clean while it is writing. It also remains in a liquid state within the tube, so that it doesn't manage to get clogged with use. These pen inks are used by the Parker Pen Company, and date back to 1923. At one point after World War II, he tried to create his own ink company, using funds from the Japanese Reparations Program. However, this proved to be unsuccessful due to political factors and post war confusion. Although pen ink is the invention that Quisumbing is most famous for, he also was an inventor throughout his lifetime.
To begin his long and illustrious career, Francisco Quisumbing attended school at the University of the Philippines, earning his BSA in 1918. He also received a Master's degree at the University of the Philippines in 1921, and a PhD in Plant Taxonomy, Systematics and Morphology at the University of Chicago in 1923. This chemical basis of his education allowed him to experiment with the botanicals and other ingredients that would help make him so successful in the pen ink business.
He then went on to work at several different universities as well, including the College of Agriculture in the Philippines. Francisco Quisumbing worked at the University of California in 1926, and then went on to become the Acting Chief of the Natural Museum Division of the Bureau of Science in Manila. During the war, he was assigned to the US Navy in a remote location at the southern tip of Samar, where he ascended with his research and attention to detail. This included restoring facilities such as the Herbarium that were destroyed during the wars in this region.
In addition to these facets of his career and work in the ink industry, Francisco Quisumbing also found the time to pen a number of morphological and taxonomic research papers. This includes an extensive account of his work with orchids, including his famous "Medicinal Plants in the Philippines," which was published in 1951. Throughout his lifetime, he managed to focus on an astounding variety of different botanical fields of research, while at the same time finding new ways to apply them in a practical manner. However, it's the invention of the Quink ink that has lasted to this day and will be his legacy.
