Jean-Baptiste Alexandre Le Blond

Jean-Baptiste Le Blond (1679–1719) was a French architect and garden designer, known in Paris for his hôtels particuliers and for a seminal treatise on formal gardens in 1709.

Invited by Peter the Great, he arrived at St Petersburg in 1716 with the title of Architect-General. He laid out workshops and nurseries along the Neva, introduced oil-lantern lighting for the main streets, and drew up an unexecuted grid plan centred on Vasilievsky Island. He helped plan the first palace and cascades at Peterhof in 1717. He died of smallpox there in 1719.
