This biography is taken from President Warren’s entry in the "Dictionary of National Biography".
Thomas Herbert Warren was born on 21 Oct 1853, the second son of Algernon William Warren and Cecil Thomas. He was educated at Manilla Hall School, Clifton, and then Clifton College.
Warren studied at Balliol College Oxford where he obtained first classes in Classical Moderations (1873) and in Literae Humaniores (1876), and won the Hertford scholarship (1873), the Craven scholarship (1878), and the Gaisford prize for Greek verse (1875). His main influence was that of Benjamin Jowett (Master of Balliol), whose ideal of a college as not merely a home of learning but a training ground for public life, was destined to guide Warren's policy in his direction of Magdalen.
In October 1877, Warren was elected to a prize fellowship at Magdalen College and succeeded in the following term to a classical tutorship. The college's President Dr. Frederic Bulley died in 1885. Warren, at the unusually early age of thirty-two, was elected President, and held the office until 1928, a period of forty-three years. He took on the task of developing the college, gathering round him a distinguished staff of teachers and welcoming as a new strength to the College the professorial fellows added by the royal commission of 1878. Meanwhile Warren was coming to hold a prominent position in University affairs. He was for many years a member of the Hebdomadal Council, a delegate of the University Museum, and a curator of the Taylor Institution. From 1906 to 1910 he was Vice-Chancellor of the University of Oxford.
Outside the university, Warren's services were employed on several government commissions and committees. The honorary degree of DCL was conferred upon him at Lord Curzon's first Encaenia in 1907, and he was also an honorary LLD of Birmingham University, an honorary DLitt of Bristol University, and an honorary fellow of Balliol (1924). The Prince of Wales (later Edward VIII) was a student at Magdalen from 1912, and the King created Warren KCVO when the prince left Magdalen on the outbreak of war in 1914.
Warren was helped in his presidential duties by his wife, Mary Isabel, youngest daughter of the chemist Sir Benjamin Collins Brodie, whom he married in 1886. The years of World War I, when he received almost daily the news of the death of some Magdalen man, brought him great distress, but he steered the college through this time of anxiety and through the period of reconstruction which followed. In 1928 age and increasing infirmity made him decide to resign: he received many tokens of affection and gratitude, and was elected an honorary fellow of the College. He continued to live in Oxford, and died there suddenly on 9 Jun 1930. He had no children.
