History

The General Assembly of the DLMPS at its Nancy congress (July 2011) agreed to an earlier DHST resolution to establish an Inter-Divisional Teaching Commission (IDTC).
​
Some background: The International Council of Scientific Unions (ICSU) was founded in 1931. It is an umbrella grouping of national and international scientific associations (physics, chemistry, geosciences, mathematics etc.). In 1945 ICSU came under the patronage of UNESCO, the cultural and educational arm of the United Nations. In 1956 the two separate member unions for history of science and for philosophy of science coalesced into the International Union for History and Philosophy of Science  (IUHPS) and as such became a member of ICSU. The disciplinary identities were retained by the creation of separate divisions within the IUHPS – the Division for History of Science and Technology (DHST), and the Division for Logic, Methodology and Philosophy of Science (DLMPS).
These divisions hold separate quadrennial congresses, and occasionally a joint congress. In 2011 at Nancy congress, the DLMPS (currently changed as DLMPST) agreed that rather than establish its own separate Teaching Commission, there should be an Inter-Divisional Teaching Commission.
