The principal literary results of his early years here were the Discours en vers sur l'homme, the play of Alzire and L'Enfant prodigue (1736), and a long treatise on the Newtonian system which he and Madame du Chatelet wrote together.
The original plan of the city, which was prepared by Major Pierre Charles L'Enfant (1755-1825), under the supervision of President Washington and Thomas Jefferson,' was a masterpiece in landscape architecture and in the main it has been preserved.
The commissioners - Thomas Johnson (1732-1819) and Daniel Carroll (1756-1829) of Maryland and Dr David Stuart of Virginia - gave the city its name; Major L'Enfant drew its plan, and Andrew Ellicott laid it out.
