Henry was born at 61 University Road,
Belfast,
Ireland, the son of the Rev Robert Mitchell Henry, a
Baptist minister (who later joined the
Plymouth Brethren), and Kate Ann Berry. Henry began studying at
Methodist College Belfast in 1882 where he first began drawing regularly. At the age of fifteen he moved to the
Royal Belfast Academical Institution. He studied art at the
Belfast School of Art before going to Paris in 1898 to study at the
Académie Julian and at
Whistler's Académie Carmen. He married the painter
Grace Henry in 1903 and returned to Ireland in 1910. From then until 1919 he lived on
Achill Island, where he learned to capture the peculiar interplay of light and landscape specific to the West of Ireland. In 1919 he moved to Dublin and in 1920, he was one of the founders of the
Society of Dublin Painters, originally a group of ten artists. Henry designed several railway posters, some of which, notably
Connemara Landscape, achieved considerable sales. He lost his sight during 1945 and did not regain his vision before his death. ==Work in collections==
