In well-established disciplines like history it is not common to find professionals who admit that they are driven by a “calling” or who say they have a “mission” to fulfill. In emerging disciplines, however, the situation is different: in order to gain recognition these new disciplines need highly driven practitioners, who’s calling enables them to overcome opposition or neglect from the side of the established disciplines. A clear example of such a practitioner with a mission in an emerging field of knowledge is the Dutch historian of science Eduard Jan Dijksterhuis (1892–1965). His career as a mathematics teacher, historical scholar, and public intellectual was marked by the desire to re-integrate science and mathematics in culture in general. Dijksterhuis regarded the history of science as a major instrument to bring about this ideal. His magnum opus, The Mechanization of the World Picture (first published in 1950 in Dutch; translated into English in 1961), was the culmination of a lifetime of writing in the service of a cultural vision that can still inspire our own generation.

Hans Freudenthal was a German-born Dutch mathematician who made important contributions to algebraic topology. He also published works on history and mathematical education.

In the late 1950's Freudenthal published several articles on the history of geometry around 1900, in particular on Hilbert's innovative approach to the foundations of geometry. Especially his essay-review of the eighth edition of Hilbert's Grundlagen der Geometrie has become a standard reference in historical studies of geometry. In the present article I discuss Freudenthal's contribution to our understanding
