In the late 1930s he broke off his studies to succeed his deceased father, who had been paymaster of the vegetable [[auction]] in Warmenhuizen. Later in 1954 he completed his studies in economics. Again twenty years later in 1973, he published his PhD thesis entitled "''Spelregels voor Economen''" ("Rules for Economists"). This methodological treatise attracted much attention and was honored in 1978 with Kluwer Price.{{Clarify|date=November 2013|reason=Should this be 'the Kluwer Prize'?}}
