International Union of History and Philosophy of Science

The International Union of History and Philosophy of Science and Technology is one of the members of the International Council for Science (ICSU). It was founded in 1955 by merging the International Union of History of Science (IUHS) and the International Union of Philosophy of Science (IUPS), and consists of two divisions, the Division of History of Science and Technology (DHST) and the Division of Logic, Methodology and Philosophy of Science and Technology (DLMPST).

The Division of History of Science and Technology (DHST) is an international non-governmental organisation devoted to international cooperation in the fields of logic and philosophy of science across the world. Together with the Division of Logic, Methodology and Philosophy of Science and Technology (DLMPST), the DHST forms one of the two divisions of the International Union of History and Philosophy of Science and Technology, representing the fields of logic, philosophy of science and history of science in the International Council for Science (ICSU).

The DHST organizes an international congress every four years, and coordinates the activities of numerous commissions. The members of DHST are 98 national members (represented by national committees for the history of science) and 26 international scientific unions.
