| Date Note | Dates of the special committee (see: GSL/COM/SP/3/3) and letters to Bowcher (see: GSL/L/S/11). |
| Administrative History | The medal is marked on the portrait side 'F B after H Pinker' which may indicate that it is based on the bust of Prestwich by Henry Richard Hope-Pinker, c.1901. A committee was set up to commission the medal in April-July 1902. The Society also lent Bowcher a portrait for reference.
The medal was first awarded to John Lubbock, Baron Avebury in 1903. |
