The Great Exhibition of 1851 excited curiosity in nineteenth-century contemporaries and continues to garner interest among scholars today. Attracting some six million visitors and comprising over 100,000 exhibits that filled 76,720 square meters of exhibition space, it entered media, memory, and historiography as an emblem of British industrial capabilities, free-trade ideology, and imperial globalization. Yet it is seldom discussed in relation to the consequential contemporaneous transformation of modern sciences into a set of powerful, highly institutionalized social practices.
Writing in 1849 from their Admiralty chambers right off of Whitehall, the Lords Commissioners of the Royal Navy issued a simple memorandum to introduce their new Manual of Scientific Enquiry, a mutable collecting reference reworked and reissued six more times over the course of the century. “Their Lordships do not consider it necessary that this Manual should be one of very deep and abstruse research,” they noted, arguing that “its directions should not require the use of nice apparatus and instruments: they should be generally plain, so that men merely of good intelligence and fair acquirement might be able to act upon them; yet, in pointing out objects, and methods of observation and record, they might still serve as a guide to officers of high attainment.” Pointing to what they considered the most important areas of research conducted overseas, the Lords Commissioners tasked fifteen of Britain’s top men of science with writing short, simple, and clear instruction booklets for naval officers, sailors, surgeons, and those elusive “professional collectors” on how and what to observe while safely bringing specimens (living and dead), notes, and records back home.
In the first week of October 1932, an International Conference on Migration Statistics was held in Geneva. Over the course of five days, some thirty statisticians from twenty-six countries discussed how to produce more reliable international migration statistics. This kind of methodological discussion about statistical standardization was not at all unusual in the new world of international organization. Since 1920, the standardization of statistics had become an ordinary activity in the “Palace” of the International Labour Organization and the League of Nations in the hills above Lake Geneva.
The International Conference on Migration Statistics offers particularly interesting insights into the historical attempt by international organizations to measure the world. On the one hand, “international migration” was not yet a category in scholarship and policy making. It was an international invention intended to bring together the existing categories of “emigration” and “immigration.” Before this time, these last two categories were perceived as two fundamentally separate phenomena. Perhaps more plainly than other objects targeted by statistical analysis, “international migration” was connected to the effort to construct a new international understanding of the world after the Great War.
