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. It became an oil boom town by 1906, when it became 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.
