Department of History and Philosophy of Science


AD HOC (Association for the Discussion of the History of Chemistry) is a group dedicated to the history of chemistry. While our main focus is historical, we also consider the philosophical, sociological, public and educational dimensions of chemistry.

AD HOC has been meeting in various configurations since the summer of 2004, first at UCL and then also in Cambridge since 2010. Since 2008 our activities have been generously supported by the Society for the History of Alchemy and Chemistry (SHAC).

Easter Term 2022

This term we will be resuming in-person meetings in Cambridge, in addition to continuing with some online meetings as we have been doing in the last two years. There will be weekly meetings starting on 2 May 2022, including online meetings roughly once a month, probably starting on 23 May. Meetings will be on Mondays at 5.00–6.30pm UK time, as before.

Further details will be announced on the mailing list of the group. Please contact Hasok Chang ( if you would like to be on the mailing list. Those on the list will receive the links for online meetings, the specification or copies of the readings, and all updates on future activities.
