Upon the formation, Pieter and Françoise Geelen chose four objectives for the foundation’s grantmaking: education, art, nature conservation and leprosy research. Nature conservation and education projects supported focus on developing countries (primarily in Africa); art projects supported take place in the Netherlands. The budget is roughly €3,500,000 per year. Since it was founded, the Turing Foundation has made donations or allocated donations for over 300 (multi-)year projects.

Turing has always been one of the heroes of our founder, Pieter Geelen. When Geelen and a friend who studied computer science together started a company in 1991, they named it the Turing Machine Company. In 2005 this company was renamed TomTom and it was listed on the Dutch stock exchange. From the proceeds of that IPO the Turing Foundation was founded.
The Turing Foundation currently has no open positions.
