Gaspard-Joseph Chaussegros de Léry (1682–1756)

It highlighted his contribution to the development of New France through the quality, variety, importance and scope of his work in the fields of military engineering, civil and religious architecture, and urban planning.

[citation needed] From his family papers kept at the National Archives of Canada, Chaussegros de Léry enjoyed the patronage of various high-ranking relatives of King Louis XV.

Throughout his life he kept up a friendly personal correspondence with Philippe II, Duke of Orléans, Louis Alexandre, Count of Toulouse, and the Duc de Penthièvre, who all expressed their affection for him and his family and assured of him of their support.

By 1716, he was employed within the Ministre de la Marine and sent to New France to prepare plans of the existing Fortifications at Quebec and to recommend those required to protect the city from attack.

This mission led to a permanent appointment as King Louis XV's Chief Engineer there, a post he held from 1719 until his death.
