The Atlas of Irish Mathematics: Monaghan (Feb 2019)

In past bimonthly Atlas of Irish Mathematics blogs with regional focus, we've shone a light on people associated with Donegal, Wexford, Armagh, Limerick, Westmeath, Mayo, Belfast, Wicklow, Kerry and Galway. This time, it's Monaghan.

Included below are men who played key roles in the early days of TCD, several Maynooth people of note, and three often overlooked people from the almost 100 Irish or Irish-based people who contributed problems or solutions to the Educational Times in the second half of the 1800s (a future blog will highlight all of them).

Comments, additions and corrections are, as always, welcome. As are more photographs of the forgotten faces from the past.

Thanks to Paul Greaney (NUIG), Olivia Bree (SPD), Tony O'Farrell (MU) & Ciarán P. Mac an Bhaird (MU), and ET Trigg for valuable input.



 1. William Clement (1707-1782) was born in Carrickmacross, Monaghan, and was educated at TCD (BA, 1726, MA 1731), where he taught for almost half a century, and also served as vice-provost. He lectured in botany, physics, and medicine at various stages of his career, and was Donegall Lecturer of mathematics from 1750 to 1759.

 2. Patrick Flood (1827?-1902) was born in Monaghan. Nothing is known about his education. He was a teacher in Wexford, Tipperary, Clare and Dublin. Over a three decade period, he contributed to the Educational Times.

 3. Physicist and mathematician Francis Lennon (1838-1920) was born in November in Tyholland, Monaghan, near the Armagh border, and was educated at Clogher. He was ordained in 1862 and appointed  professor at the diocesan seminary St Macartan's.  Following the death of Nicholas Callan in 1864, he became professor of natural philosophy in Maynooth, a position he held until 1911.  He served terms as chair of the Dublin Scientific Club and examiner for mathematics for the Intermediate Education Board.  He has 2 books to his name: the revised and improved 1872 edition of André Darré's Elements of Geometry with Both Plane and Spherical Trigonometry, and The Elements of Plane and Spherical Geometry (1875).

 4. Francis Tarleton (1841-1920) was born in Monaghan, and was educated at TCD (BA 1861, MA 1865) where he was elected a fellow in 1866.   He was called to the bar is 1868, but spent his entire career as ad academic and administrator at TCD.  He occupyied the chair of natural philosophy from 1890 to 1901, treating physics as a branch of maths, and also served as bursar, senior dean, and vice provost, and was awarded an honorary ScD (1891).  He authored books on dynamics and the mathematical theory of attraction, and contributed to the Educational Times.  He colourfully viewed Einstein's theory of relativity as being in the same category as Bolshevism.

 5. William Stoops (1844?-1919) was born in Castleblayney, Monaghan, and was educated at Queen's College Cork (BSc 1874).  At first he taught at the Coleraine Academic Institute, then in 1881 he became the headmaster at the Newry Intermediate School, where he stayed until 1917.  He contributed to the Educational Times.

 8. Doctor William A. Stoops (1869-1938) was born 20 February in Mullyash just outside Castleblayney, Monaghan.  He was educated at Queen's Belfast (BSc 1897, MD 1903??) and practised medicine in England.  He was one of the main mourners at the funeral of William above who died in 1919, and may have been a cousin of James above.

 9. James "Max" Henry (1887?-1947) was born ?? in Monaghan. He was educated at TCD (BA & Gold Medal 1909, MA 1914) and was on the maths staff there from 1914 (when he was one of the last two men to be elected Fellow by examination) to his death. He published a controversial book A New Fundamentalism in 1934 and later served as junior dean. Roy Johnston's appreciation linked below is entertaining.

11. Eoghan Rushe (1917-2001) was born in Corduff, northwest of Carrickmacross, Monaghan.  He was educated at UCD (BSc 1939) and later taught at Belcamp College in Dublin, where he rose to the rank of vice principal. (Thanks to Bernie Ruth & Joe Callan for valuable input here.)


12. Roy Nelson (1920-??) was born in Carrickmacross in Monaghan. He taught maths at UCD 1956-1959. More information is welcome. (He is not the Open University presenter of the same name who previously taught computer science at QUB in the 1960s.)


13. Paul Carragher (1927-1999) was born 28 June born near Annyalla, Castleblayney, Monaghan.  He joined the civil service for a few years, and was then educated at TCD (BAI 1955, MA 1960).  He worked for 2 years as an engineer in Scotland and England, and then taught maths at Izmir Koleji in Turkey.  Moving to Canada in 1958, he taught at Memorial University in Newfoundland until 1966, then for a year at TCD.  Most of the rest of his career (1968-1993) was spent at the University of New Brunswick, also in Canada.  He received his doctorate from TCD (1978) for a thesis on "Heat Transfer on Continuous Solid Surfaces" done under Lawrence Crane.

His current interests include maths education, the history of mathematics, and algebraic number theory.


17. Jack McDonnell was born in Castleblayney, Monaghan, and was educated entirely at Maynooth (BSc 2013, MSc 2014, PhD 2019).
