|Preserving the history
of the O'Fallon area
|A very brief history of O'Fallon
Though Native American settlement dates back centuries, O’Fallon’s first modern-day settlement
was made in 1802 by Revolutionary War veteran Capt. Joseph Ogle. Others soon followed, lured
by rich land well suited to agriculture. It was here that John Mason Peck founded Rock Spring
Seminary in 1827, the first college in Illinois. Within 25 years, coal mining had begun and the Ohio
& Mississippi Railroad was built. The town began as O’Fallon Station, a depot of the O & M
Railroad, named for railroad president Col. John O’Fallon of St. Louis, a nephew of George Rogers
Clark and William Clark. The first lots were sold at public auction on May 13, 1854. The first public
school was built in 1861. O’Fallon was incorporated as a village in 1874 and converted to city
government in 1905. The Community Park was established in 1924 and a public library in 1930.
Scott Air Force Base, founded in 1917, contributed to much of O’Fallon’s growth and I-64 fueled its
rise as a commercial center. O’Fallon is the birthplace of actor William Holden and illustrator Bernie
Fuchs. Today, at over 25,000, O’Fallon is one of the fastest growing cities in the St. Louis area.
