He was born in toulouse in southern France and left France for Hispaniola (Santo Domingo) at the beginning of the French Revolution. He lived on Hispaniola and worked as an engineer until 1794, when he was forced to flee by the uprising of 1794. He moved to the United States and published a renowned plan of Philadelphia in 1796, along with a second edition in 1802. Varlé lived in Maine in 1795, and later in Massachusetts. He again lived in Philadelphia from 1797-98, and then moved to Baltimore, where he spent the rest of his days, except for time spent in Philadelphia in 1802.
