Шаблон:Short description Шаблон:Infobox scientist Abraham Cornelis Sebastiaan "Bram" van Heel (17 July 1899 – 18 May 1966) was a Dutch professor of physics at the then TH (now TU) Delft. He is regarded as the 'father of technical optics in the Netherlands'.

Biography

Heel was born in Central Java as the son of Abraham Louis Cornelis van Heel, who was born in Düsseldorf, Prussia in 1867 and was the founder and director of the oil factories 'Insulinde' in the Dutch East Indies.[1]

Heel studied physics at Leiden, where he graduated and obtained his doctorate in October 1925 with Wander de Haas for his thesis.[2]

During his studies he spent a year in Paris, in the laboratory of Charles Fabry, the co-inventor of the Fabry-Pérot interferometer, among other things.[3] He also attended lectures there with Henri Chrétien, known, among other things, for the Ritchey-Chrétien telescope.Шаблон:Citation needed

Heel owed his good knowledge of French to this stay in Paris, which contributed to his later international fame in the optical field.[3] Van Heel is best known for his easy-to-apply calculation methods for the design of optical systems and their application in concrete designs.[3] In addition, he was a good teacher. With his students, he designed optical instruments for the observatory of Utrecht University.[3] He was also active in various international forums in his field. For example, he was co-founder of the International Commission for Optics (ICO) (1948) and of the trade magazine Optica Acta (1954), the predecessor of the current Journal of Modern Optics.[4]

He was one of the founders of two companies in Delft, namely the Optical Industry “De Oude Delft” (later Шаблон:Ill), and Nonius, which made precision instruments and later merged with Enraf into Шаблон:Ill).[1]

He wrote the well-known textbook Introduction to optics, which for many years was the standard textbook in this field at Delft University of Technology, among others.[1]

Two sons were born from his marriage to Huberta (Zus) Meerburg, Abraham Lodewijk Sebastien, married to Dr AMCT Kasteel, former member of the House of Representatives of the States General and Prof. Huib van Heel, former professor at TU Delft.

In 1965 he uttered the words: "The light always comes from the left, except when it comes from the right."Шаблон:Citation needed This quote is still prominently displayed at the ImPhys Optica research group at TU Delft.Шаблон:Citation needed
