British Pre-Raphaelite painter, writer and collector. Henry Wallis was admitted as a probationer to the Royal Academy and enrolled in the Painting School in March 1848. After two years, he pursued his training in Paris in the atelier of the Swiss painter Marc Gabriel Charles Gleyre (1806–1874) and at the École des Beaux-Arts. In 1854, he exhibited at the Royal Academy in London and continued to do so regularly until 1877. In 1878, he was elected an Associate of the Royal Society of Painters in Water Colours and a full member of the Royal Watercolour Society in 1880.
Wallis was an expert in Islamic ceramics (see for instance Wallis 1885, Wallis 1893, Wallis 1894, Wallis 1899), which he also collected, together with other Islamic artefacts, among them stucco and glass windows. In 1896, he sold six windows to the Glasgow Museums (IG_288–IG_292).
