## History

Kiefer was originally known as "Praper" when a post office was first established in 1901. The St. Louis, Oklahoma and Southern Railway (later the St. Louis and San Francisco Railway) constructed a line south from Sapulpa through Praper between 1900 and 1901. The route is today operated by BNSF. Praper became an oil boom town by 1906, when it grew into a major shipping point for crude from the Glenn Pool field. The post office was renamed "Kiefer" on December 12, 1906. According to the Encyclopedia of Oklahoma History and Culture, the name honored at least one of three different people named Kiefer who lived in the area.
Kiefer voted to incorporate on November 20, 1908. The 1910 census reported a population of 1,197 inhabitants. This increased to 1,663 in 1920.
In the early days, Kiefer was on the route of the Sapulpa & Interurban Railway (“S&I”) streetcar/interurban line connecting to Tulsa through Sapulpa; S&I subsequently went through a series of mergers and name changes, with only the Tulsa-to-Sapulpa portion continuing as the Tulsa-Sapulpa Union Railway.
The Kiefer Searchlight was a weekly newspaper published in Kiefer that included local, state, and national news along with advertising. 123 issues from 1908 to 1911 are available online.
In the 21st century, Kiefer is mostly a commuter town, with 94.6 percent of workers living in town commuting to jobs elsewhere, primarily in Tulsa. However, it is also headquarters for Bridge Crane Specialists, a company involved in the design, manufacturing, installation, and servicing of overhead and work station crane systems.
Kiefer is the site of an extensive residence known to locals as the Kiefer Castle, having been built to resemble a fairy-tale castle.
