Cincinnati was founded in 1788 by John Cleves Symmes and Colonel Robert Patterson. 
Surveyor John Filson (also the author of The Adventures of Colonel Daniel Boone) named it "Losantiville" from four terms, each of different language, meaning "The city opposite the mouth of the Licking River." "Ville" is French for "city," "anti" is Greek for "opposite," "os" is Latin for "mouth," and "L" was all that was included of "Licking River."
In 1790, Arthur St. Clair, the governor of the Northwest Territory, changed the name of the settlement to "Cincinnati" in honor of the Society of the Cincinnati, of which he was a member.
The society honored General George Washington, who was considered a latter day Cincinnatus—the Roman general who saved his city, then retired from power to his farm. 
To this day, Cincinnati in particular, and Ohio in general, are home to a disproportionately large number of descendants of Revolutionary War soldiers who were granted lands in the state.
In 1802, Cincinnati was chartered as a village and David Ziegler (1748-1811), a native of Heidelberg, Germany, who fought in the Revolutionary War became the first Mayor. 
Cincinnati was incorporated as a city in 1819. 
The introduction of steam navigation on the Ohio River in 1811 and the completion of the Miami and Erie Canal helped the city grow to 115,000 citizens by 1850.
On April 1, 1853, Cincinnati's Fire Department became a paid department, the first full-time paid department in the United States, and the first in the world to use steam fire engines.
