Geological Society Club , 1824-

The Geological Society had originally formed as a 'Geological Dinner Club' at the Freemason's Tavern, Great Queen Street, London, on the 13 November 1807. However whilst the Society flourished, attendance at the Dining Club rapidly declined. A fine of 10s 6d was imposed for non attendance without prior warning, but by 1809 the total stood at £37 16s of which only £6 6s had been received. By around 1811, meetings of the Club had ceased.

The present Club was revived in 1824 by 30 members of the Society, some of whom had attended the previous Club. The first meeting was held at the Thatched House Tavern, St James' Street, on 5 November 1824. The rules on establishment limited membership to 40, however this number was never achieved during its early years and was reduced to 36 members in 1836. From 1904, the membership was gradually raised and by 1999 stood at 202 members.

Fellowship of the Society was, from the first, an essential qualification, however subsequent classes of supernumerary and honorary ranks were introduced later. Guests could be invited, unless the dinners were 'closed meetings' which could only be attended by Club members. In 1973, it was decided that most of the dinners, except for closed meetings, could be open events, that is attended by any Fellow of the Society.

Traditionally, meetings were held on the evenings of every Ordinary Meeting of the Society, but are now monthly.
