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.

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

[2] At Leiden University he became inspired by Nobel Prize laureates Hendrik Lorentz and Heike Kamerlingh Onnes, the latter eventually becoming his promotor.

[citation needed] Van Heel owed his good knowledge of French to this stay in Paris, which contributed to his later international fame in the optical field.

[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.
