Thomas Hoccleve or Occleve was a key figure in 15th-century Middle English literature, significant for promoting Chaucer as "the father of English literature", and as a poet in his own right. His poetry, especially his longest work, the didactic work Regement of Princes, was extremely popular in the fifteenth century, but went largely ignored until the late twentieth century, when it was re-examined by scholars, particularly John Burrow. Today he is most well known for his Series, which includes the earliest autobiographical description of mental illness in English, and for his extensive scribal activity. Three holographs of his poetry have survived, and he also copied literary manuscripts by other writers. As a clerk of the Office of the Privy Seal, he wrote hundreds of documents in French and Latin.
Thomas Hodgskin was an English socialist writer on political economy, critic of capitalism and defender of free trade and early trade unions. In the late 19th and early 20th centuries, the term socialist included any opponent of capitalism, at the time defined as a construed political system built on privileges for the owners of capital.
Thomas Holcroft was an English dramatist, miscellanist, poet and translator. He was sympathetic to the early ideas of the French Revolution and helped Thomas Paine to publish the first part of The Rights of Man.
Thomas Hood was an English poet, author and humorist, best known for poems such as "The Bridge of Sighs" and "The Song of the Shirt". Hood wrote regularly for The London Magazine, Athenaeum, and Punch. He later published a magazine largely consisting of his own works. Hood, never robust, had lapsed into invalidism by the age of 41 and died at the age of 45. William Michael Rossetti in 1903 called him "the finest English poet" between the generations of Shelley and Tennyson. Hood was the father of the playwright and humorist Tom Hood (1835–1874) and the children's writer Frances Freeling Broderip (1830–1878).
Thomas Hughes was an English lawyer, judge, politician and author. He is most famous for his novel Tom Brown's School Days (1857), a semi-autobiographical work set at Rugby School, which Hughes had attended. It had a lesser-known sequel, Tom Brown at Oxford (1861).
