Father John Schoenmakers, S.J. founded Osage Mission on April 28, 1847. Called the "Apostle to the Osage" and the "Father of civilization in Southeast Kansas," he served for 36 years as spiritual director, doctor, steward, lawyer, judge, catechist and preacher to the Osage. He served as an officially appointed U.S. postmaster of Osage Mission from 1851 to 1864. With the relocation of the Osage he ministered to the needs of the newly arrived settlers. He built the present St. Francis Church stone structure. Father Schoenmakers is buried in St. Francis Cemetery one quarter mile east of the Church.
