The first individuals to own the land upon which Basehor now stands were Thomas S. and Mary Z. Townes. The couple bought it from the railroad in 1873 and mortgaged it to Ephraim Basehor the same year. On January 9, 1874, the Townes sold the 160 acres to Basehor.
Basehor, Kansas, located in Leavenworth County, was founded in 1889 by Reuben Basehor and his brother Ephraim. They both were of Pennsylvania Dutch descent and came to Kansas in 1854. After living in Lawrence for a time, Ephraim began working as a hired hand for an area farmer. He eventually bought the farm and other land holdings in the area.
In 1889, the railroad was completed and Ephraim plotted his land and began building the town site. It was dedicated on November 30, 1889, and was named after Mr. Basehor.
Ephraim Basehor donated the land for the school house around 1900. The old grade school was located north of town and was originally called the Prairie Garden District #32. The first high school classes in the community met in 1905 above the Kemler-Hammond General Store. In 1906, a building was erected to house the high school and grade school. It was built for K-12 on the southeast corner of 155th Street and Leavenworth Road. The high school was upstairs, and K-8 was located in the three classrooms downstairs. In 1929, there were 5 graduates.
Reuben Basehor donated $1,000 to the school to build a library which was a cement structure east of the old school. A new two-story brick high school was built as a W.P.A. project in 1938. The grade school classes continued to be held in the old building until a new grade school was built in 1955. By 1963, a new high school was built, and the older building was taken over by the top two grades of the grade school.
