The London Mathematical Society, as part of its 150th anniversary celebrations, is running a project entitled Local Heroes, in which they have encouraged and funded local museums to put on exhibits about mathematicians from their area. The funding was allocated in 2014, and during 2015 various exhibits have been taking place in different parts of the UK, each celebrating a local number hero.
EDIT: the Lincoln exhibit has been extended until 3rd November – details below.
Here’s a list of all the exhibits currently open for visitors:
Lincoln, England: featuring George Boole, originally at Lincoln University Library – extended until 3rd November at Lincoln Cathedral
Parts of the LMS website also mention an exhibit in Banff, but I can’t find any information about it.
