In 2016–2017 the Centre for History and Philosophy of Science at the University of Leeds celebrated its 60th anniversary. Since 1956, the Centre has been one of the few institutions promoting the study of science from a combined historical and philosophical perspective (other such departments include the HPS departments in Cambridge, Indiana, and Pittsburgh, and the IHPST in Paris and Toronto, to name a few). 1 The editors of this volume viewed this anniversary as an opportunity to reflect on the legacy, the current state, and the future of Integrated History and Philosophy of Science (iHPS).
