Henry Jackson, mercer, and was a ‘kinsman’ of Anthony à Wood. On 1 Dec. 1602 he was admitted scholar of Corpus Christi College, Oxford, ‘having for years before been clerk of the said house,’ and proceeded B.A. 1605, M.A. 1608, B.D. 1617. In 1630 he succeeded his tutor, Dr. Sebastian Benefield [q. v.], as rector of Meysey Hampton, Gloucestershire. His death at Meysey Hampton, on 4 June 1662, is noted by Wood in his diary. Wood, who attended the funeral, speaks of Jackson as one of the earliest of his learned acquaintances, and says that ‘being delighted in his company, he did for the three last yeares of his life constantly visit him every summer’ and took notes of Jackson's recollections of the Oxford of his youth.
In 1607 Dr. Spenser, president of Corpus Christi College, employed Jackson in transcribing, arranging, and preparing for the press ‘all Mr. Hooker's remaining written papers,’ which had come into Spenser's possession shortly after Hooker's death [see Hooker, Richard]. Jackson printed at Oxford in 1612 in 4to Hooker's answer to Walter Travers's ‘Supplication,’ and four sermons in separate volumes; of that on justification a ‘corrected and amended’ edition appeared in 1613. Two sermons on Jude, doubtfully assigned to Hooker, followed, with a long dedication by Jackson to George Summaster, in the same year. After Spenser's death, in April 1614, Hooker's papers were taken out of Jackson's custody, but he would seem to have supervised the reprints by William Stansby, London, of Hooker's ‘Works,’ in 1618 and 1622, which included the above-mentioned ‘Opuscula’ and the first five books of the ‘Ecclesiastical Polity.’ The preface, with Stansby's initials, is conjectured to be Jackson's. When Hooker's papers were taken from Jackson's care, he was engaged upon an edition of the hitherto unpublished eighth book of the ‘Polity,’ and complained (December 1612) that the president (Spenser) proposed to put his own name to the edition, ‘though the resurrection of the book is my work alone’ (‘a me plane vitæ restitutum’). Keble suggests that Jackson, aggrieved by Spenser's treatment, retained his own recension of Hooker's work when he delivered up the other papers, and that when his library at Meysey Hampton was plundered and dispersed by the parliamentarians in 1642, his version of book viii., or a copy of it, came into Ussher's hands. It is now in the library of Trinity College, Dublin, and has been made the basis of the text printed in Keble's editions of Hooker's works.
Besides his editions of Hooker's Sermons, Jackson published: 1. ‘Wickliffes Wicket; or a Learned and Godly Treatise of the Sacrament, made by John Wickliffe. Set forth according to an ancient copie,’ Oxford, 1612, 4to. 2. ‘D. Gulielmi Whitakeri … Responsio ad Gulielmi Rainoldi Refutationem, in qua variæ controversiæ accurate explicantur Henrico Jacksono Oxoniensi interprete,’ Oppenheim, 1612. 3. ‘Orationes duodecim cum aliis opusculis,’ Oxford, 1614, 8vo. Jackson's lengthy dedication to Summaster is inserted after the first two orations, which had been previously published. 4. ‘Commentarii super 1 Cap. Amos,’ Oppenheim, 1615, 8vo, a translation of Benefield's ‘Commentary upon the first chapter of Amos, delivered in twenty-one sermons.’ 5. ‘Vita Th. Lupseti,’ printed by Knight in the appendix to his ‘Colet,’ p. 390, from Wood's MSS. in the Ashmolean Museum. Besides these printed works Jackson projected editions of J. L. Vives's ‘De corruptis Artibus’ and his ‘De tradendis Disciplinis,’ and of Abelard's works. The rifling of his library destroyed his notes for these works, but Wood mentions as extant ‘Vita Ciceronis, ex variis Autoribus collecta;’ ‘Commentarii in Ciceronis Quæst. Lib. quintum’ (both dedicated to Benefield); translations into Latin of works by Fryth, Hooper, and Latimer. Jackson collected the ‘testimonies’ in honour of John Claymond [q. v.] prefixed to Shepgreve's ‘Vita Claymundi,’ and translated Plutarch's ‘De morbis Animi et Corporis.’ Among Wood's MSS. are ‘Collectanea H. Jacksoni,’ regarding the history of the monasteries of Gloucester, Malmesbury, and Cirencester.

JACKSON, HENRY (1831–1879), novelist, born at Boston, Lincolnshire, on 15 April 1831, was son of a brewer. After attending Sleaford and Boston grammar schools, he was placed first in a bank, and subsequently in his father's brewery. Severe illness left him an invalid for life at eighteen, and he devoted himself thenceforth to literary work. He died at Hampstead on 24 May 1879. Jackson's earliest stories were published in ‘ Chambers's Journal,’ beginning with a brief tale called ‘A Dead Man's Revenge.’ His first novel, entitled ‘A First Friendship,’ was published in ‘Fraser's Magazine’ while Mr. J. A. Froude was editor; it was reissued in one volume in 1863. His next novel, ‘Gilbert Rugge,’ appeared in the same magazine, and was published in three volumes in 1866.
