The Atlas of Irish Mathematics: Clare (Feb 2021)
Our 23rd bimonthly regional Irish focused blog highlights mathematical people associated with Clare, following on Donegal, Wexford, Armagh, Limerick, Westmeath, Mayo, Belfast, Wicklow, Kerry, Galway, Monaghan, Tipperary, Sligo, Carlow, Down, Cork, Cavan, Laois, Londonderry, Meath, Leitrim, and Dublin.
The proximity of Clare to Galway has resulted in good access to third level education for students from the county since Queen's College Galway (later UCG and now NUIG) was founded in the mid 1800s. There are more options now of course, including the University of Limerick (formerly NIHE Limerick), which has really blossomed since the 1980s. Over the decades, many Clare students chose Cork too. Curiously, three early maths trained men associated with Clare had careers in the RIC.
As usual, there are probably Irish maths (or maths ed or stats or actuarial or theoretical physics) people missing from this blog because while we know about them we don't yet know they are from Clare.
Comments, additions and corrections are, as always, welcome. As are more photographs.
