Thomas (Tom) Jones, CH (27 September 1870 – 15 October 1955) was a British civil servant and educationalist, once described as "one of the six most important men in Europe", and also as "the King of Wales" and "man of a thousand secrets".
Thomas Jones was born on 27 September 1870, at 100 High Street, Rhymney, Monmouthshire. He was the first of nine children to David Benjamin Jones and Mary Ann Jones. His family was Welsh speaking but by the time he was school age, the family usually spoke English except for Sunday School and the chapel. Welsh was banned at school and Jones later wrote that "outside the chapel, I never had a lesson in Welsh". His fluency in Welsh in later life was hindered by this but his command of English was excellent. He as educated at the Upper Rhymney School and Lewis School in Pengam. Jones had failed to win a scholarship at Lewis but his father could afford the school fee.
Jones's grandfather insisted on his leaving school at 14 to work as a clerk in the local ironworks. Jones complied but his interest in reading and his facility in public speaking brought him fame as a preacher. In 1890 he won the Calvinist Methodist scripture gold medal and proceeded to the University College of Wales at Aberystwyth to study for the ministry. New interests intervened, however; and Jones eventually graduated with first-class honours in economics from the University of Glasgow in 1901.
In 1902 he married a student from his time at Aberystwyth, Eirene Theodora Lloyd (1875–1935), daughter of Dr Richard John Lloyd, Reader in Phonetics at Liverpool University. There were three children from the marriage : Eirene White (1909–99), who became a Labour Minister under Harold Wilson (1966–70), Tristan (1913–90), who became managing director of The Observer, and Elphin, who died in a motoring accident in 1928.
Jones pursued at first an academic career after graduation from Glasgow. He was Russell Student at the London School of Economics; Barrington Lecturer in Ireland (1904–05); Assistant to the Professor of Political Economy and Lecturer in Economics at Glasgow; and Professor of Economics, Queen's University, Belfast, 1909–10.
He became familiarly known as "T.J." He was Deputy Secretary to the Cabinet under four Prime Ministers: Lloyd George, Andrew Bonar Law, Stanley Baldwin and Ramsay MacDonald. His 3-volume Whitehall Diary (1969, 1971) threw much light on politics "behind the scenes", including the Irish Treaty, the 1926 General Strike, the meetings between Lloyd George and Adolf Hitler, the Cliveden Set, and so on. In 1914 he had started the magazine Welsh Outlook to promote social progress in Wales.
