Jean-Baptiste Alexandre Le Blond (1679 – 10 March 1719) was a French architect and garden designer who became the chief architect of Saint Petersburg in 1716. Career in France He was the son of Jean Le Blond, painter in ordinary to the king, a printseller on the Pont Saint-Michel, Paris, and his wife, Jeanne d'Eu. He studied architecture with his mother's brother Jean Girard, in the service of Philippe I, duc d'Orléans. Jacques-François Blondel implied that he had derived gardening expertise from André Le Nôtre, finding that Le Blond was one of our Architects, who among us most knew how to profit from the precepts of the great Master...

As theoretician and illustrator of architecture, Le Blond produced the second (1710) and third (1720) editions of the Cours d'architecture de Vignole translated with commentary by Charles-Augustin d'Aviler, which Le Blond illustrated with his own drawings. These works introduced the distinctions between state apartments (appartements de parade) and private apartments (appartements de commodités) that would characterize French eighteenth-century planning, and he popularized the small chimneypieces that would take the place of the large ones in the Italian mode, popular in the previous century.
