Macquart was born in Hazebrouck, France in 1776 and died in Lille in 1855. He was interested in natural history from an early age due to his older brother who was an ornithologist and a Fellow of the Société de Sciences de l’Agriculture et des Arts de la Ville de Lille and whose bird collection became the foundation of the societies museum, the Musée d'Histoire Naturelle de Lille. A second brother founded a botanic garden with a collection of over 3000 species of plants. Macquart, too became interested in natural history. In 1796 he joined the staff of General Armand Samuel then campaigning in the Revolutionary Wars. He was a secretary and draftsman. The general staff was stationed in Schwetzingen, then Heidelberg, Mainz, Arau, Basel and Zurich.He left the army in 1798 returning to Lille with German books, insects and birds.

He then worked full-time on insects and studying in the library and on 27 Nivôse, Year 11 of the French Revolutionary Calendar (1802) he was elected a Fellow of the Société de Sciences de l’Agriculture et des Arts de la Ville de Lille. Soon he began travelling around France and went several times to Paris where he met Pierre André Latreille who suggested to specialize on Diptera, following the pioneering work of Johann Wilhelm Meigen. After some time in Holland he married and moved from Hazebrouck to Lestrem where he became a Conseillers régionaux of the Conseil régional du Nord-Pas-de-Calais.
