Born in 1798 in Whitehaven, England, he migrated to Halifax in 1818.[1] In 1822 he married Susannah Smith there, with whom he had two daughters. He married again in 1830 to Sarah Sellon. He died on December 26 in 1849 and was buried at Camp Hill Cemetery, Halifax.
Career
From 1819 he worked as a portrait painter, teacher, and painter of signs and architectural ornaments.[2] In his early career, Valentine also worked as a house painter in periods that saw less commissions.[3] He filled a void left by portrait painter Robert Field who had practiced in Halifax from 1808 to 1816. Valentine painted his subjects in a naturalistic, plain style distinct from that of contemporary European portraitists.[3] His portraits often featured black-clad sitters against dark backgrounds.[3]
Valentine studied painting in England in 1836, after which his work visibly improved.[2] In 1839 he travelled to Paris where he learned the Daguerreotype process, an early form of photography, of which he was a pioneer in Canada as early as 1842.[2] Valentine was a mentor and later a business partner of the photographer Thomas Coffin Doane.[4]
