Imperial, MO
Early 1800's
The modern village of Imperial, located in Rock Township in the northeast corner of Jefferson County, was founded in the 1800's, but this was not the first time the area west of Kimmswick had been inhabited. Evidence has shown that it was once the site of a prehistoric Native American village. Excavations of the area north of Rock Creek (directly behind Bethesda General Baptist Church) suggests that these prehistoric residents used the mineral springs for processing salt. Imperial is also the home of Mastodon State Historic Site where the bones of spear points of ancient inhabitants of the area are found.
The town was carved from a Spanish Grant given to Francis Labarge in the early 1800's. Many of the modern towns in Jefferson County started out with one name, and then changed to another over the years. The little community of Imperial was once called West Kimmswick, Liberty, and then Rockport before the present name of Imperial stuck. The name came from a clock factory that only existed about 2 or 3 years in a concrete building on the Bayer Garden property during World War 1, called the Imperial Clock Company.
The population of the town grew after 1904 when E.J. White and his wife, the former Margaret Miller, decided to open a general store. Mr. White, a mail carrier at Beck (now a part of Arnold), who was born and raised in Jefferson County, built the store with the help of his brother, William White. On April 15, 1904, he opened the general store and saloon (now Herrell's Market). Although the Frisco railroad ran nearby, there was no switch station; so White decided to build one. Before long, White convinced the railroad to make a stop at his depot, and the town began to prosper. A post office was established, and settlers built homes and businesses there. Local children were educated at either St. John's Catholic School or White School. In 1938, the new consolidated Windsor school was built south of Imperial on U.S. Hwy 61.
Today, Imperial is one of the fastest growing communities in Jefferson County. Residents enjoy the suburban setting of homes nestled in the rolling hills, but have easy access to the interstates and highways leading to St. Louis.
