Foundation and activities

Foundation ‘Stichting’ Gebrs. De Jong’s Leen is founded in 1921. Its main task is managing the estate of the De Jong brothers. Their inheritance became available to descendants for educational purposes. The foundation management includes keeping a family tree to make this possible.

The board

The board consists of:

  • Herre Kingma – Chairman
  • Klaas-Jan van Dijk – Treasurer
  • Birgit ten Cate – Secretary
  • Eelco de Graaf – Inspector study progress
  • Martin de Vries – Member of the board


The foundation disburses amounts of money, so called grants, to descendants of Mr Herre Rinia en Mrs Reinskje van der Sluis who are following a educational course, want to graduate or otherwise want to achieve an educational goal.

Descendants who believe they qualify for a grant must submit a completed application to the secretary of the foundation. The application form is only available for descendants and is only made available if the Board has started a application procedure. Whether one is descendant will be – among other ways – verified by consulting the family tree which is managed by the Foundation. A grant will be awarded after a positive decision made by the board of the foundation.
