== Biografie ==&lt;br /&gt;
(Poortvliet 24 mei 1910 - &amp;#039;s-Gravenhage 20 februari 1973). Directeur Deltadienst.&lt;br /&gt;
Burgemeesterszoon uit Poortvliet; R.H.B.S. Bergen op Zoom; wis- en natuurkunde Rijks Universiteit Leiden. Dissertatie: &amp;#039;Over stratifieerbare congruenties&amp;#039; (1939);  vijf van zijn elf stellingen betroffen de getijden. In 1934 in dienst van Rijkswaterstaat onder Dr.lr. Joh. van Veen om de wiskundige behandeling der getijden en wat daarmee samenhing in detail ter hand te nemen. Werd getypeerd als de eerste &amp;#039;wiskundige ingenieur&amp;#039; in Nederland. Buitte als hoofdwiskundige zijn bekwaamheden uit bij de droogmaking van Walcheren in 1945 en daarna bij de herstelwerkzaamheden na de stormvloed van 1953. Werd in 1963 hoofd van de waterloopkundige afdeling van de Deltadienst en in 1968 directeur van de Deltadienst. Had een belangrijk aandeel in de studie getijberekeningen Deltaplan. (Bijdrage III, deel 4, 1960; Bijdrage IV-2, deel 5, 1961; en in samenwerking Bijdrage IV-3, deel 5, 1961 rapport Deltacommissie.) Zijn wiskundige kennis resulteerde in de ontwikkeling van verschillende berekeningsmethodieken, waarmee een wetenschappelijke basis werd gelegd voor een groot aantal wetmatigheden die tot dan een empirisch karakter hadden. Daardoor werd het mogelijk consequenties van waterbouwkundige ingrepen vooraf te analyseren en een rationeel beleid op waterbouwkundig gebied te ontwikkelen. Zijn hoofdwerk &amp;#039; Tidal computations in rivers and coastal waters&amp;#039; (1964) mag als mondiaal standaardwerk voor de theorie van de getijberekeningen beschouwd worden. In 1965 ontving hij daarvoor de Conradmedaille van het Kon. Ned. Instituut van Ingenieurs.&lt;br /&gt;
