André-Adolphe-Eugène Disdéri French, 1819-1889 Disdéri is best known as a portraitist and popularizer of the carte-de-visite. He spent 10 years as a painter and working in the theater, and another five in the clothing business, before becoming seriously interested in photography around age 30. He first operated studios in Brest and Nîmes, then moved to Paris and opened a studio in 1854, and a second in 1863. In 1854 Disdéri patented the carte-de-visite, a method of producing a number of small images on a single negative that achieved great popularity. He later opened additional studios in London, Madrid, and Toulon. Disdéri was one of the best known portrait photographers of his day, with many important commissions and sitters. Like Mathew Brady, he was an innovator and entrepreneur as well as an artist. The carte-de-visite, which he did not invent, but rather adapted, helped photography to become increasingly versatile as a medium and available to people of all means. In 1879 Disdéri sold his business and moved to Nice. Despite his success, he died 10 years later in Paris in poverty, obscurity, and poor health. T.W.F.
