The Atlas of Irish Mathematics: Meath (Aug 2020)
Our 20th bimonthly regional Irish focused blog highlights mathematical people associated with Meath, following on Donegal, Wexford, Armagh, Limerick, Westmeath, Mayo, Belfast, Wicklow, Kerry, Galway, Monaghan, Tipperary, Sligo, Carlow, Down, Cork, Cavan, Laois (formerly Queen's County).
Of course the best known Irish mathematical person associated with this eastern county was Dubinborn Hamilton. Then, it seems, there is a very big gap before the next Meath maths person. There are very few people overall, especially for a large county just north of the capital. One reason is probably that there are Irish maths people who are from Meath but not yet identified by us as being from there.
Comments, additions and corrections are, as always, welcome. As are more photographs.

1. Ireland's greatest mathematician and mathematical physicist William Hamilton (18051865) was born 4 August in Dublin. He grew up mostly in Trim, Meath, from the age of 3. He was educated at TCD (BA 1827, MA 1837, LLD 1839), where he spent his whole career. His extensive legacy includes innovations in algebra, mechanics and optics. He invented quaternions, a noncommutative algebraic system predating matrices. Wikipedia / MacTutor / TCD / DIB / Papers / Enc Brit / Enc / Hamilton Walk 

2. Astronomer and and astrophysicist Mary Conway (aka Máire Ní Chonmhidhe, later Brück, 19252008) was born 29 May in Ballivor, Meath, and was educated at first in physics at UCD (BSc 1945, MSc 1946), earning an NUI Travelling Studentship. She went to Edinburgh (PhD 1950), her thesis on "Studies of Hα Line Profiles in Prominences" being done under Irishman Mervyn Ellison). She had actually been at Dunsink since 1947, and in 1957 moved to a position at the Royal Obs Edinburgh with husband Hermann Brück (see above) when he was appointed as director of the Royal Obs there. She also held a position at Univ Edinburgh (19721987). Her extensive publications include the books The Night Sky (1965), Agnes Mary Clerke and the Rise of Astrophysics (2002) and Women in Early British and Irish Astronomy: Stars and Satellites (2009).

His thesis on "The Design and Analysis of Mixed Grazing Experiments" was done under Gordon Foster. After a spell at Teagasc he joined UCD, where he served for 25 years, including a stint as head of statistics His research interests are in agricultural and ecological and biological statistics, and he supervised several PhD students.
