Ferryman between two cultures: The calling of a historian of science.

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).
