“To understand a science, it is necessary to know its history.”
Augustus Comte (1798-1857)

HOGG (The History of Geology Group) exists to encourage interest in the history of geology, and the events and personalities that have shaped the way in which it is studied and practised today.

For details of our latest news and topical snippets on the history of geology please follow our Twitter feed (which can also be seen on the left of this page).

Membership is open to anyone with an interest in the development of knowledge about the earth and geology and how this has been represented (e.g. through geological maps). There is no requirement to be a Fellow of the Geological Society of London or have any other geological credentials, and we encourage interest from young people.

HOGG members are a network of knowledgeable enthusiasts who exchange and discuss information and queries about history of geology matters via a dedicated online mailing list.

HOGG holds at least three meetings each year, and members are eligible for reduced registration fees. From time-to-time other meetings and other activities are added to HOGG’s programme.

Details of forthcoming HOGG meetings can be found here.

HOGG produces occasional publications based on collection of themed papers from meetings and other topics relating to the history of geology, edited by HOGG members.

For further details and how to join please see the Join Us page.

HOGG is affiliated to the Geological Society of London


Forthcoming Meeting:

Aug 2020 - Edward Greenly and the Geology of Anglesey – a centenary meeting – CANCELLED

2020 marks one hundred years since the publication of the Geological Survey map of Anglesey. The memoir ‘The Geology of Anglesey’ was published the year before. Both these were the work of Edward Greenly, with the support of his very able wife, Annie, over the previous 25 years to map the geology of Anglesey in great detail. Greenly was the master of mapping at six inches to the mile, and he would produce a book on ‘Geological Surveying’ a decade later that would become a standard in how to do geological mapping.
