Stichting Wiskunst Koos Verhoeff

Info

De stichting heeft tot doel:

• het conserveren van wiskunstige objecten ontworpen door Koos Verhoeff;

• het verzamelen, analyseren, catalogiseren, beheren, en onder de publieke aandacht brengen van deze objecten en eraan gerelateerde zaken.

Koos Verhoeff is emiritus hoogleraar informatica aan de Erasmus Universiteit Rotterdam. Hij studeerde wiskunde in Leiden en Amsterdam, promoveerde op het gebied van de coderingstheorie, en werkte bij het Mathematisch Centrum (tegenwoordig CWI), de TU Delft, Philips, en de Erasmus Universteit Rotterdam. Naast het bedenken van (abstracte) dingen is hij is altijd geïnteresseerd geweest in (concreet) construeren.
