      • Bartholomew Lloyd (5 February 1772 – 24 November 1837) was an Irish mathematician and academic who served as the 27th Provost of Trinity College Dublin from 1731 to 1737. His entire career was spent at Trinity College Dublin. As Erasmus Smith's Professor of Mathematics there, he promoted significant curricular reforms, including the introduction of the teaching of calculus.


      Early life and education


      Lloyd was born in New Ross, County Wexford, on 5 February 1772. He was the son of Humphrey Lloyd, the son of the Rev. Bartholomew Lloyd of the Abbey House of New Ross. His father died while he was still a boy, and an uncle, the Rev. John Lloyd, rector of Ferns and Kilbride, to whose care he had been given, also died shortly so that he was left to struggle for himself. He entered Trinity College Dublin in 1787 as a pensioner. In 1790, he was elected a Scholar of the College; in 1792, he graduated B.A. in 1796 and obtained a junior fellowship. He graduated M.A. in the same year, B.D. in 1805, and D.D. in 1808.


      Academic career


      In 1813, Lloyd was appointed Erasmus Smith's Professor of Mathematics on the resignation of Professor William Magee, and in 1822, Erasmus Smith's Professor of Natural and Experimental Philosophy in succession to Professor William Davenport. In both chairs he made a radical change in the methods of teaching. He was the first to introduce French mathematical innovations into Trinity College, including the teaching of calculus.
      In 1821, and again in 1823, and 1825, he was elected regius professor of Greek in the university, and in 1823, and again in 1827, Archbishop King's lecturer in divinity. In 1831, he was elected Provost of the college, in succession to Samuel Kyle who became bishop of Cork and Ross.
      Trinity's magnetic observatory was founded through Lloyd's influence. In 1835, he was appointed president of the Royal Irish Academy, and in the same year acted as president of the British Association meeting at Dublin. His inaugural address dealt mainly with "the correspondence of the objects of science with divine revelation".
      Lloyd died suddenly of apoplexy on 24 November 1837 and was buried in the college chapel. The Lloyd Exhibitions were founded by subscription in 1839 in his memory. A marble bust of him by Thomas Kirk stood in the library of Trinity College.
