Very happy to have presented at @nationalarchives.gov.uk.web.brid.gy today as part of their 'Talking Records' symposium! Met some great people and heard some great pollution history research!

Thrilled to be presenting at #IMC2026 alongside some really excellent papers on policing the premodern urban environment! Expect lots of court leet rolls, dung heaps, and blocked gutters! @imc-leeds.bsky.social

Excited to announce that I'll be giving a paper at the National Archives' symposium, Talking Records: Pollution in the Archives on the 4th December. Expect some interesting pollution history discoveries that I've found using the court leet rolls from medieval Peterborough and Ramsey!

The Greenhouse @unistavanger.bsky.social is launching an international Masters Program in Public Environmental Humanities from fall 2026! Taught in English. Please share with all your students, #envhist #envhum colleagues! Learn more about the program here: www.uis.no/en/studies/t...

Once again I'm back at the British Library looking at rolls! This morning I came across a particularly damaged roll with large chunks of it having been ripped off. To keep the roll secure, the British Library had wrapped it with a 19th century application form to buy railway shares as scrap paper!

In addition to visiting archives, I am currently preparing to attend a summer school at the University of Bern next week! It will be a really exciting course on the digital humanities and medieval history which I hope will introduce me to some new methods I could use in my research. L.H. #envhum

These court rolls tell me what medieval communities considered a crime. We see instances of individuals being fined for dumping dung heaps, blocking gutters, selling unclean meat, and being irresponsible with their fires. L.H. #envhum

Today I'm at the National Archives in Kew! There are a small number of court rolls stored here instead of the British Library. As I'm only in London for a few weeks, I will be taking photos of the rolls so I'm able to analyse them in more detail later. L.H. #envhum

This week I am on a research trip in London where I will be going to the British Library and National Archives! Currently I am looking at some account rolls from Ramsey Abbey to see if the Abbey was funding the construction/repair of sewers, gutters, or latrines. L.H. #envhum

My research is on waste management and sanitation in late medieval English towns, focusing on the responsibilities, expectations, and levels of accountability for town officials! L.H.

Hello #envhum! My name is Louis Henry and I'll be doing the Greenhouse account takeover this week! I am a PhD candidate in medieval environmental history and I started at UiS this year. L.H.
