Last week I went to a conference on gasholders. I have been researching gas industry history for many, many years and we have a large and important (and probably doomed) holder just down the road. I used to sit at Council meetings with a little paper model of a gas holder on my desk – the only person who noticed it was Chris Roberts (and he laughed, he did, honestly).
The conference was organised by the Institution of Gas Engineers — and the industry is one that doesn’t really recognise people who don’t work for it (never has) but they did allow specialist historians like me to go. But they did get us all to stand up at the start so we could be identified as the aliens among them.
