Held on average once a month in the Conversation Room, these allow Hist members to deliver a paper on literally any topic that is of interest to them regardless of how eccentric or unknown it may be. Previous Derby speeches include the influence of the Godfather on the real-life Mafia, the future of commercial space exploration and depictions of women in fairytales (pretty diverse material, as you can see).
The setting for Derbies is informal; speeches can be up to seven minutes and afterwards the audience is given the chance to ask the speaker questions on their topic – often the most entertaining and heated part! There is also a drinks and snacks reception afterwards. These events are open to all Hist members, no matter how involved they are in the society and are always popular, thanks to their frequently funny and interesting (read: weird) subjects!
