## History

Smithville is named after Humphrey "Yankee" Smith (1774 – May 5, 1857) after he settled at the site in 1822. The town was originally known as "Smith's Mill" but ultimately became "Smithville" as it was easier to pronounce. Another reputed history behind the name is that it was going to be named Smith's Mill, but there was already another current settlement in Missouri with the same name so it was altered slightly to differentiate it.
Silver Screen stars Wallace Beery and Noah Beery, Sr. were born and raised near Smithville.
The Aker Cemetery and Downtown Smithville Historic District are listed on the National Register of Historic Places.
