The Netherlands is commonly described as a latecomer to the quantitative revolution. Dutch spatial science coincided with the societal transformation of the late 1960s that included the professionalization, upscaling and democratization of higher education. Although these changes profoundly changed Dutch human geography, lumping together this transformation with the quantitative revolution largely erased the memory of an earlier phase of Dutch quantitative geography in the 1950s. This earlier wave originates in Dutch geography's engagement with applied research by sociologists, urbanist-engineers and economists in the immediate post-1945 period. In the urgency of post-war rebuilding, in which geographers found a significant source of employment, quantitative methods were debated and welcomed to speed up the survey process in spatial planning. The chapter describes how quantitative methods took root in Dutch geography in these two waves in the 1950s and 1960s, and discusses why the first has been largely forgotten. While the 1960s generation performed the quantitative revolution as taught by anglophone textbooks, the emergence of quantitative geography got caught up with the democratization movement in higher education. Resultantly, the conception of the Netherlands as latecomer became lodged in the historiography.
