Hugh Seymour Tremenheere (1804–1893) was an English academic, barrister, publicist and author, who worked as a schools inspector and mines inspector.
He was born at Wootton House, Gloucestershire, on 22 January 1804, the son of Walter Tremenheere and his wife Frances Apperley; Charles William Tremenheere (1813–1898) of the Royal Engineers was his brother. He was educated at Winchester School from 1816, and matriculated as a scholar from New College, Oxford, on 30 January 1824. He was a fellow of his college from 1824 to 1856, graduated B.A. 1827 and M.A. 1832, and was called to the bar at the Inner Temple on 21 November 1834.
After three years' practice as a barrister, Tremenheere was made a revising barrister on the western circuit.
Tremenheere entered public service, and was sent in 1839 to Newport to investigate John Frost's rebellion. He subsequently served on numerous Royal Commissions, and was instrumental in bringing about fourteen Acts of Parliament with social aims.
In January 1840 Tremenheere was appointed an inspector of schools. He was a member of the Central Society of Education, and his appointment came about through the support of Baldwin Francis Duppa, the Society's secretary. He was the first British schools inspector, with his colleague Rev. John Allen, who represented the Committee for Council on Education. He made nine reports to the committee of the council on education on the state of schools in England and Wales. He found, however that his right to free comment in reports was in practice curtailed, and resigned the post. The problem arose in January 1842, with his report on 66 school of the British and Foreign School Society. He came under political pressure to withdraw from Lord Wharncliffe, but refused to alter the report.Joseph Fletcher took over as inspector for the British and Foreign School Society, from 1844.
