Chinese Engineers Relational Database (CERD) Bi-monthly Export

This is a bi-monthly export. CERD is a database of engineers from the Chinese Republican period (1912–1949). CERD-Taiwan describes engineers active in the early post-war period (1945–1974). Based on various digitised historical sources, it is a prosopographic catalogue of individuals, their education and their employment, and the institutions connected with it. Most biographical events have geographical information attached to them. The data can be used freely by researchers to answer individual research questions.
