Mathematical Professorships at Trinity College Dublin (Nov 2019)

Trinity College Dublin has had four historical named chairs of mathematics and related areas, three of them with names suggesting a focus in natural philosophy (aka physics) or astronomy. They are:

Since Ireland's most distinguished mathematician ever, William R. Hamilton, held only the last position, clearly one should pay attention to all holders of these chairs.

Note: the official terms of office holders are sometimes longer than people served, and are not always tied to academic years. Some people listed as serving until a particular year may have died very early in that year, or have resigned the previous year. Replacements were not always appointed immediately. Also, months of appointment are known to vary from January to November, and those appointed later in a year may not have taken up their post until the following calendar year.

These 4 chairs and many of those who held them are well documented in David Spearman's pioneering "Mathematics at TCD 1592-1992: 400 years of Mathematics". As is pointed out there, when discussing these professorships, most of the people who held these positions were mathematically minded.

Indeed, Ireland's most distinguished mathematical scientist, William Hamilton, was professor of astronomy. Here is the TCD record of his enrolling there on 7 July 1823 , just four weeks before his 18th birthday. His line is the eighth one, listed as "Gulielmus Hamilton", the first line being Bartholomew Lloyd (whose middle name was Clifford), son of mathematician Bartholomew Lloyd and brother of Humphrey who are both highlighted in this blog. The images here are at TCD online here and here.

Closer inspection of Hamilton's line reveals later annotations in red: factus est Soc: Com: Jussii Propositi & Soc: Sen: Junii die 16 A:D: 1827 et codem die ab iis electus est Astronomiae Professor, referring to his being formally appointed professor on Saturday, 16 June 1827.

The second edition of Dublin Evening Post that very day heralded his appointment:

He still had final exams to sit on 19 & 20 June. Graduation was on Tuesday, 10 July, when 69 BAs were conferred. Back in June, while still technically an undergraduate, Hamilton had already had to exercise one professorial duty: "examining graduates in the higher branches of mathematics for Bishop Law's mathematical premium."

There are two errors in the TCD entrance record above which would perpetuate in future documents: the listing of Meath (East) as Hamilton's birthplace and the implication that his solicitor father Archibald (1778-1819) was still alive (it was customary to use defunctus when it was known that a father was deceased).

Those errors are for instance listed in the standard work of reference for TCD graduates up to 1860: Alumni Dublinensis: A Register of the Students, Graduates, Professors and Provosts of Trinity College in the University of Dublin, 1593–1860 edited by G.D. Burtchaell & T.U. Sadleir (Dublin, 1935), where on page 366 we see:

No adjustments are suggested in the Addenda and Corrigenda section at the end of that volume. Note that there are later versions of Alumni Dublinensis (e.g., 1881) which account for post-1860 graduates. More TCD entrance and matriculation records may be explored here.

In one sense, what follows below is an expansion of a chronological accounting of all the scientists in Spearman's 4 lists, updated past 1992 as appropriate.

Some of the resulting 62 men (there were no women) also had a term as Donegall Lecturer, a title that was in use regularly from 1675 to 1944 (and on and off again since 1967). Usually that appointment preceded appointment to a professorship, occasionally it came later, and in one case it ran more or less concurrently. A future blog will survey all of the very numerous Donegall Lecturers.

Selection of winning candidates for professorships was not always without controversy, as this January 1870 report shows:

Comments and corrections are, as always, welcome. As are more images of people featured here.

Thanks to Olivia Bree (St Pat's, Drumcondra) once more for considerable genealogical assistance, and sourcing of newspaper articles. David Spearman (TCD), David Malone (MU) and Luke Drury (DIAS) provided crucial clarification on numerous matters. Anne van Weerden (Utrecht) also made valuable contributions and suggestions, including drawing our attention to Hamilton's TCD records discussed and depicted above, and supplying some images of people.

19. APA03 William Rowan Hamilton (1805-1865) was born 3/4 August in Dublin, and grew up there and (from the age of 3) in Trim, Meath. He was educated at TCD (BA 1827, MA 1837, LLD 1839). He was appointed the third Andrews Professor of Astronomy (and hence effectively Royal Astronomer of Ireland and Director of Dunsink) a few weeks before his BA graduation, and held those positions until his death. He is Ireland’s most renowned mathematician and mathematical physicist. His extensive legacy includes innovations in algebra, mechanics and optics. He is perhaps most well known for quaternions, a non-commutative algebraic system predating matrices. Cambridge awarded him LLD in 1845 and DCL in 1861. He was the first Foreign Associate of United States National Academy of Sciences.

43. ESPM15 Charles Rowe (1893–1943) was born 5 February in Cork city, and was educated at first at UCC (BA 1913, MA 1914), where he won an NUI Travelling Studentship Prize.  He moved to TCD (Scholar 1914, BA & Large Gold Medal 1917, Fellow 1920), and spent 1920-1921 in Paris, studying under Hadamard, Lebesgue, and Goursat. Upon his return to TCD he was made acting Professor of Maths; he was also Donegall Lecturer in Maths (1923-1926). He served as Erasmus Smith's Prof of Maths (1926-1943), until his untimely death.  He had supervised TCD's first mathematical PhD student (1932), and he also spoke at ICM that year.

48. ESPNEP18 Physicist Ernest Walton (1903–1995) was born in Dungarvan, Waterford, and his family moved around Ireland a great deal when he was young. He first studied maths and physics at TCD (BA 1926, MSc 1927 by thesis under JL Synge). At Cambridge, he engaged in research which culminated in a PhD under Ernest Rutherford in 1931. His "splitting the atom" with John Cockroft lead to the two men later sharing a Nobel prize. He lectured at TCD for four decades, from 1946–1974 as Erasmus Smith's Prof of Natural & Experimental Philosophy.
