Trinity College, Dublin in the context of "City of Literature"

David Allardice Webb (12 August 1912 – 26 September 1994) was an Irish botanist and chair of botany at Trinity College, Dublin from 1949 to 1966. He was son of George and Dr Ella Webb. In Ireland he had studied under Henry Horatio Dixon and also studied in the United Kingdom. In addition to botany he edited a history of Trinity College with R. B. McDowell and published a book on the history of art in Trinity College. In 1982 he received the Boyle Medal of the Royal Dublin Society. His botanical specialties included his work as a leading taxonomist of Saxifraga. He died in a car accident on his way to the University of Reading's herbarium. The eighth edition of An Irish Flora was renamed Webb's An Irish Flora in his honour.

Major-General Patrick Ronayne Cleburne (/ˈkleɪbɜːrn/ KLAY-burn; March 16, 1828 – November 30, 1864) was a senior officer in the Confederate States Army who commanded infantry in the Western Theater of the American Civil War.

Born in Ireland, Cleburne served in the 41st Regiment of Foot of the British Army after failing to gain entrance into Trinity College of Medicine, Dublin in 1846. He served at Fort Westmorland on Spike Island and was present on the island in 1849 when Queen Victoria visited Cork Harbour. Three years after joining the Army, he immigrated to the United States. At the beginning of the American Civil War, Cleburne sided with the Confederate States. He progressed from being a private soldier in the local militia to a division commander. He participated in many military campaigns, especially the Battle of Stones River, the Battle of Missionary Ridge and the Battle of Ringgold Gap. He was also present at the Battle of Shiloh. Known as the "Stonewall of the West", Cleburne was killed leading his men at the Battle of Franklin.

Sir Thomas Manly Deane (8 June 1851 – 3 February 1933) was an Irish architect, the son of Sir Thomas Newenham Deane and grandson of Sir Thomas Deane, who were also architects.

Born at Ferney House, Blackrock, Cork, on 8 June 1851, he was educated at Trinity College, Dublin, and travelled in France and Italy before joining his father's practice in 1878. Deane later went into partnership with his father from 1884 until his father's death in 1899, when he joined Sir Aston Webb. He designed three buildings of note in Dublin: the National Museum and National Library on Kildare Street and also in the 1937 Reading Room in Trinity College Dublin. Deane was knighted in 1911. He died in Wales on 3 February 1933, aged 81.

What Is Life? The Physical Aspect of the Living Cell is a 1944 science book written for the lay reader by the physicist Erwin Schrödinger. The book was based on a course of public lectures delivered by Schrödinger in February 1943, under the auspices of the Dublin Institute for Advanced Studies, where he was Director of Theoretical Physics, at Trinity College, Dublin. The lectures attracted an audience of about 400, who were warned "that the subject-matter was a difficult one and that the lectures could not be termed popular, even though the physicist’s most dreaded weapon, mathematical deduction, would hardly be utilized." Schrödinger's lecture focused on one important question: "how can the events in space and time which take place within the spatial boundary of a living organism be accounted for by physics and chemistry?"

In the book, Schrödinger introduced the idea of an "aperiodic solid" that contained genetic information in its configuration of covalent chemical bonds. In the 1940s, this idea stimulated enthusiasm for discovering the chemical basis of genetic inheritance. Although the existence of some form of hereditary information had been hypothesized since 1869, its role in reproduction and its helical shape were still unknown at the time of Schrödinger's lecture. In 1953, James D. Watson and Francis Crick jointly proposed the double helix structure of deoxyribonucleic acid (DNA) on the basis of, amongst other theoretical insights, X-ray diffraction experiments conducted by Rosalind Franklin. They both credited Schrödinger's book with presenting an early theoretical description of how the storage of genetic information would work, and each independently acknowledged the book as a source of inspiration for their initial researches.

Brian C. McGing is a papyrologist and ancient historian, who specialises in the Hellenistic period. He was Regius Professor of Greek at Trinity College, Dublin until his retirement in 2017. He served as editor of the college's journal of the classical world, Hermathena.

In 2004, McGing was elected a Member of the Royal Irish Academy (MRIA).

Henry Horatio Dixon FRS (19 May 1869, Dublin – 20 December 1953, Dublin) was a plant biologist and professor at Trinity College Dublin. Along with John Joly, he put forward the cohesion-tension theory of water and mineral movement in plants.

He was born in Dublin, the youngest of the seven sons of George Dixon, a soap manufacturer and Rebecca (née Yeates) Dixon. He was educated at Rathmines School and Trinity College, Dublin. After studying in Bonn, Germany he in 1894 he was appointed assistant and later full Professor of Botany at Trinity. In 1906 he became Director of the Botanic gardens and in 1910 of the Herbarium also. He had a close working relationship with physicist John Joly and together they developed the cohesion theory of the ascent of sap.
