Mary Hays (1759–1843): Writer. Brought up in a Dissenting home in London, she first found fame with her Cursory Remarks on an Enquiry into the Experience and Propriety of Public Worship (1792). This propelled her into the circle of radicals around the publisher Joseph Johnson (1738–1809; DNB). Hays’s Memoirs of Emma Courtney (1796) gained her some notoriety, as it was a thinly-disguised version of her relationship with the radical William Frend (1757–1841; DNB).

Benjamin Robert Haydon (1786–1846): Painter and diarist. Southey admired his work and corresponded with Haydon whilst working on an article for the Quarterly Review on Haydon’s New Churches, Considered with Respect to the Opportunities they Offer for the Encouragement of Painting (1818).

Joseph Haslewood (1769–1833): London solicitor, who became a well-known bibliographer and antiquary. He edited many early English texts and created a very important collection of ephemeral literature. Southey corresponded with him about the works of Thomas Chatterton (1752–1770; DNB).

Aaron (fl. 1820s–1850s) Hartwell (or Hartnell): In early 1824 Southey was elected as an Honorary Member of the Bristol Literary and Philosophical Society and Hartwell corresponded with him on this matter, as he was the organisation’s Secretary. Local directories describe Hartwell as a ‘Professor of Mathematics’ and he contributed papers on astronomy to the Bristol Literary and Philosophical Society.

John Harris (1756–1846): Publisher, who mainly specialised in juvenile books. In 1813, in collaboration with C. J. Barrington, he ventured into new territory and suggested that Southey should take up the continuations of John Campbell’s (1708–1775; DNB), Lives of the Admirals and Other Eminent British Seamen (1742–1744). Southey immediately declined the offer on the grounds of his inadequate knowledge of the subject.

Julius Charles Hare (1795–1855): Writer and Church of England clergyman. He was born in Valdagno, Italy, the son of the historian, novelist and playwright, Francis Hare-Naylor (1753–1815; DNB) and his wife Georgiana (c. 1755–1806). His maternal aunt, Anna Maria (1748–1829; DNB), was the widow of the orientalist Sir William Jones (1746–1794; DNB). The family returned to England in 1799. What became a lifelong interest in German literature and scholarship began with Hare’s visit to Weimar in 1804. He matriculated at Trinity College, Cambridge, in 1812, graduated B.A.

Francis George Hare (1786–1842): Brother of Julius Hare and Augustus William Hare (1792–1834; DNB), clergyman, tutor at New College, Oxford, and historian. The brothers were the sons of Francis Hare-Naylor (1753–1815; DNB), historian, novelist and playwright. Francis George Hare lived mostly on the Continent and was a close friend of Walter Savage Landor. He visited Southey at Keswick in 1827; Southey commented ‘Never did I see a man possessed of such exuberant spirits’.

Samuel Carter Hall (1800–1889): Journal editor and writer. He was born at Geneva barracks, County Waterford, where his father, Robert Hall (1753–1836), was an officer in the Devon and Cornwall Fencibles. In c. 1802 the family moved to Topsham in Devon but later returned to Ireland. Hall developed an early interest in literature and the arts. His first poem was occasioned by the death of his eldest brother, Revis, at the battle of Albuera in 1811. In 1822 Hall moved to London.

Justus Hiddes Halbertsma (1789–1869): Minister in the Mennonite Church in the Netherlands and leading figure in the creation of a literary tradition in West Frisian. He was born in Grou in Friesland, the son of a baker, and trained at the Mennonite seminary in Amsterdam 1807–1813, before becoming a Minister in Bolsward 1814–1821 and Deventer 1822–1856. Halberstma and his two brothers issued the first collection of folk tales in Western Frisian, De Lapekoer fan Gabe Skroar, in 1822, and the collection was reissued and expanded throughout his lifetime.
