Located approximately eight miles south of Okmulgee and six miles north of Henryetta in Okmulgee County, just off U.S. routes 75 and 62, the original name of the town may have been Winchell. The town was added along the route of the St. Louis, Oklahoma and Southern Railway (later the St. Louis–San Francisco Railway, or Frisco) built between Okmulgee and Henryetta in 1900. The post office built in August 1903 was named for Matt Schulter, said to be a resident of St. Louis, Missouri. Coal mining in the Henryetta Coal Formation was an important early industry in the area, and attracted many nationalities of European immigrants. Early Schulter, circa 1909, had three coal company offices, phone service, a school, a general store, and even a pool hall for its 200 residents. Later, the town benefitted from oil exploration, production, and refining. The town's peak population may have been circa 1930, at 650 people. The town did not officially incorporate until May 5, 1998.
