Étienne Sulpice Hallet

Étienne Sulpice Hallet was a French-born U.S. architect. Around 1789, Hallet went to the United States. There he became known as Stephen Hallet. He worked as Pierre L'Enfant's draftsman. Hallet submitted plans for the future Capitol in Washington, D.C. in form of a giant dome to Thomas Jefferson. However, the design of William Thornton was favored in 1793. Hallet then worked as supervisor for Thornton, until he tried to force some of his own designs.
