David 'Davy' Adriaan van Dorp (Amsterdam April 27, 1915 - Vlaardingen February 19, 1995) was a Dutch chemist.
Van Dorp was born as the son of Hendrik van Dorp and Maria van Dorp, and studied chemistry in Amsterdam where he received a PhD for his thesis Aneurine en gistphosphatase in 1941.
In 1946, while employed by the Dutch Organon company in Oss, Van Dorp and Jozef Ferdinand Arens ('Coco') published the synthesis for vitamin A acid in the scientific journal Nature. In 1947, they completed the first full synthesis for the complex compound vitamin A, by taking the final step and turning the acid in an alcohol. Their synthesis was not to be used for commercial production, as an alternative route that was published soon after by Otto Isler and co-workers (Hoffmann-La Roche) turned out to be much more suited for upscaling.
Van Dorp joined the Unilever Research Laboratory in Vlaardingen in 1959, and was a key person in the studies regarding the role of arachidonic acid in the metabolic pathway to prostaglandin E2, in close cooperation with Sune K. Bergström who would later receive a Nobel prize for his work on prostaglandins.
Famous quotes containing the words david and/or van:
“As I came home through the woods with my string of fish, trailing my pole, it being now quite dark, I caught a glimpse of a woodchuck stealing across my path, and felt a strange thrill of savage delight, and was strongly tempted to seize and devour him raw; not that I was hungry then, except for that wildness which he represented.”
—Henry David Thoreau (1817–1862)
“The variables of quantification, ‘something,’ ‘nothing,’ ‘everything,’ range over our whole ontology, whatever it may be; and we are convicted of a particular ontological presupposition if, and only if, the alleged presuppositum has to be reckoned among the entities over which our variables range in order to render one of our affirmations true.”
—Willard Van Orman Quine (b. 1908)
