Augustin Francois de Macarty or McCarthy (January 10, 1774 – October 16, 1844) was an American planter who served as the sixth mayor of New Orleans from September 4, 1815, to May 13, 1820.
[1][2] He was a member of an influential Creole family that was allied by marriage to Esteban Rodríguez Miró, one of the last Spanish Governors of Louisiana.
His tenure was chiefly marked by the first officially recorded outbreak of yellow fever, and the subsequent creation of the city's first Board of Health in 1817.
In 1819, the city's first public waterworks system was begun; its execution was entrusted to Benjamin Henry Latrobe, who succumbed to yellow fever there himself, the following year.
During Macarty's tenure, the population of New Orleans grew from 33,000 to 41,000; and commerce, measured by Mississippi boat traffic and receipts, doubled.
