Shaping demographies. The statistician, economist and demographer Robert René Kuczynski in Germany, USA and Greatbritain, 1890-1950

该项目涉及19世纪90年代至50年代之间人口学作为一门独立学科的兴起。它的目的是通过重建人口学学科面临的限制和面临的竞争，确定为这一新兴科学的制度化铺平道路的各种过程。人口学学科在20世纪30年代之前基本上是在壁外存在的。其目的是阐明它的认知、概念和方法基础，以及关于人口思维的变化，简而言之，就是它的动态塑造。作为一项在跨国和国家比较层面上运作的科学史研究，该项目本着拉图尔的《追随演员》的精神，以经济学家、统计学家和人口学家罗伯特·勒内·库钦斯基(Robert RenéKuczynski，1876-1947)的生活和工作为起点。从20世纪20年代开始，他的净生育率概念使他成为新兴人口统计学的先驱。除了他们的传记相关性，库钦斯基S的跨国网络，在某些情况下，全球网络提供了不同的洞察力，涉及到塑造他那个时代的人口统计过程。该项目包括两项独立研究，以库钦斯基为例，调查解决人口问题的参与者和机构动态网络的变化。这些研究的主要来源是Robert RenéKuczynski在柏林Zentral-und Landesbibliothek的庄园，在德国研究基金会的支持下存档，该基金会拥有与该项目所述问题有关的宝贵材料。它还辅之以各种国家和国际档案馆的材料。

The project deals with the emergence of demography as an independent discipline between the 1890s and the 1950s. It aims to identify the various processes that paved the way for the institutionalisation of this emerging science by reconstructing the limits to and competition faced by the discipline of demography, which led a largely extra-mural existence up to the 1930s. The intention is to throw light on its cognitive, conceptual and methodological foundations as well as on the changes in thinking about population, in a nutshell on its dynamic shapings. Designed as a science history study operating at both a transnational and national comparative level, the project is conducted in the spirit of Latour's follow the actor and takes as its starting point the life and work of the economist, statistician and demographer, Robert René Kuczynski (1876-1947). From the 1920s his concept of the net reproduction rate made him a pioneer of the nascent demographies. Apart from their biographical relevance, Kuczynski s transnational and in some cases global networks provide diverse insights into the processes involved in shaping demographies in his time. The project comprises two independent studies which, taking Kuczynski as an example, investigate the shift in the dynamic networks of players and institutions in which population questions were tackled. The primary source of the studies is Robert René Kuczynski's estate in the Zentral- und Landesbibliothek Berlin, archived with the support of the German Research Foundation, which has valuable material relating to the issues addressed in the project. It is complemented with materials from various national and international archives.
