Joop Klant

In the late 1930s he broke off his studies to succeed his deceased father, who had been paymaster of the vegetable auction in Warmenhuizen.

Again twenty years later in 1973, he published his PhD thesis entitled "Spelregels voor Economen" ("Rules for Economists").

Just after the Second World War Klant left for South Africa, where he worked as statistician for eight years in Pretoria.

From 1966 until 1975 Klant was director of SEO Economic Research as successor of Jacobus Franciscus Haccoû.

In Pretoria on 24 January 1948 Joop Klant married Anna Joana (Jacqueline) Faljan Vlielander Hein (born 1911).
