Federico van der Hoeven: Federico van der Hoeven (Born in 1951) is a Spanish former motorcycle racer and auto racing driver.  Van der Hoeven raced motorcycles, formula cars and rally cars throughout the 1970s and 1980s.  Van der Hoeven was born in Brussels, Belgium to a Dutch father and a Spanish mother.

Van der Westhuizen: van der Westhuizen (also known as van der Westhuisen, van der Westhysen) is a common Afrikaans surname.  The largest number of van der Westhuizens can be found in Africa, but because of immigration large numbers of van der Westhuizens can also be found in Argentina, Australia, United Kingdom, Canada, New Zealand and the United States of America.  Van der Westhuizens have had a notable influence on every significant phase of South African history, most notably the Great Trek, First Boer War and the Second Boer War, as well as strategic campaigns in both World Wars.

Van der Waals surface: The van der Waals surface of a molecule is an abstract representation or model of that molecule, illustrating where, in very rough terms, a surface might reside for the molecule based on the hard cutoffs of van der Waals radii for individual atoms, and it represents a surface through which the molecule might be conceived as interacting with other molecules.  Also referred to as a "van der Waals envelope," the van der Waals surface is named for Johannes Diderik van der Waals, a Dutch theoretical physicist and thermodynamicist who developed theory to provide a liquid-gas equation of state that accounted for the non-zero volume of atoms and molecules, and on their exhibiting an attractive force when they interacted (theoretical constructions that also bear his name).  van der Waals surfaces are therefore a tool used in the abstract representations of molecules, whether accessed, as they were originally, via hand calculation, or via physical wood/plastic models, or now digitally, via computational chemistry software.  Practically speaking, CPK models, developed by and named for Robert Corey, Linus Pauling, and Walter Koltun, were the first widely used physical molecular models based on van der Waals radii, and allowed broad pedagogical and research use of a model showing the van der Waals surfaces of molecules.

Renger van der Zande: Renger van der Zande (born 16 February 1986 in Dodewaard, Gelderland) is a Dutch race-car driver.  He is the son of the 1978 National Dutch Rallycross Champion with VW Golf Mk1 1600, the Psychologist Ronald van der Zande.  In 2016, van der Zande won his first major sports car championship with co-driver Alex Popow and Starworks Motorsport in the WeatherTech SportsCar Championship PC Class.  Renger resides in Amsterdam with his partner Carlijn and their daughter.

Van der Waals strain: In chemistry, van der Waals strain is strain resulting from van der Waals repulsion when two substituents in a molecule approach each other with a distance less than the sum of their van der Waals radii.  Van der Waals strain is also called van der Waals repulsion and is related to steric hindrance.  One of the most common forms of this strain is eclipsing hydrogen, in Alkanes.

Jan van der Vaardt: Jan van der Vaardt (name variations: Jan van der Vaart, John Van der Vaart, John Vander Vaart, Jan van der Waart) (c.1650 –1727) was a Dutch painter of portraits, landscapes and trompe-l'œil paintings and a mezzotint artist who was active in England for most of his career.
