Henry Clark Pidgeon was an English painter in water-colours and antiquary.
Pigeon practised as an artist and teacher of drawing in London. In 1847 he moved to Liverpool, where he was professor of the school of drawing at the Liverpool Institute, gave private lessons, and drew local scenes and antiquities. He became a member of the Liverpool Academy of Arts in 1847, and was its secretary in 1850. He was a non-resident member from then to the reconstruction of the academy in 1865.
With Joseph Mayer and Abraham Hume, Pidgeon in 1848 founded the Historic Society of Lancashire and Cheshire. He and Hume were joint-secretaries till January 1851, when Pidgeon moved back to London. There he continued his practice as a painter and a teacher of art. He had been elected an associate of the Institute of Painters in Water-colours in 1846, and a full member in 1861. He was also president of the Sketching Club.
Pidgeon died at University College Hospital, London on 6 August 1880, in his seventy-fourth year and was buried with his wife Jane, who died the same year, on the eastern side of Highgate Cemetery. Very little of their gravestone (plot no.23912) is now visible.
