Henry Harris also attended Thomas Wright Hill's Hilltop School, which was located in central Birmingham, a short distance from the family's home on Temple Row West.
[3] Between 1818 and 1846, he exhibited eighteen works at the Royal Academy in total, exceeding in number those of Samuel (senior) and Frederick Thomas Lines (Henry's youngest brother) combined.
He remained a Member until approximately 1856, and was listed as an annual subscriber from 1858 onwards, alongside his younger brothers, Frederick Thomas and Edward Ashcroft.
He had sixteen works accepted in the first exhibition – all landscapes and topographical views of Yorkshire, North Wales and the Midlands.
Worcester was previously seen as lacking in intellectual activity, as highlighted by Henry Harris' school friend Edwin Lees who originally trained as a printer and stationer but later turned to the sciences and natural history.
Geoffrey Potter notes in Henry's biography that Lees, upon visiting Worcester in 1828, noticed 'Worcester's lack of the societies and institutions necessary for a man of refined intellect', which 'was remedied by a Mr. Jackson, who delivered a course of lectures on the subject of Natural Philosophy'.
He spent much of his later years surveying his local Malvern Hills, meticulously taking measurements and visually recording the ancient and physical features.
Besides his surveys of the Malvern Hills, he was also known to travel alone to North Wales every summer to explore the ancient stone monuments.
