Meservey was founded in 1886, shortly after a railroad line was built connecting Mason City and Fort Dodge. It takes its name from the Meservey brothers, who were railroad employees at this time. The western portion of town was originally known as Kausville, and eventually merged into Meservey, and is still legally known as the "Kausville Addition".

The Consolidated Independent School District of Meservey, Iowa was seeking a builder for its school in the 1920s. The Meservey school building was built in the 1940s as a K-12 facility for Meservey High school. In 1963, it became an elementary and junior high school for the combined Meservey–Thornton school district. At a later time it became elementary school only as junior high classes were moved to Thornton. Due to declining enrollments, the building was closed in 1983, when all K–12 classes met in the Thornton facility. In 1988, Meservey–Thornton began whole-grade sharing with Sheffield–Chapin school district. The Meservey school facility was razed sometime around 1993, and the property is now Schoolhouse Park. Meservey High School's mascot was the Rockets. The Meservey-Thornton mascot was the "Lancers". When the high school classes moved to Sheffield in 1988, the Lancer mascot was retained for the middle-school sports teams. However, with further consolidation in 2007, the Lancer mascot was officially retired with a parade in Thornton in July, 2007. Due to continued declining enrollment, the former S-C, M-T, and neighboring Rockwell–Swaledale school districts entered into a grade-sharing agreement to form the West Fork school partnership in 2008, with the "Warhawks" as the new mascot. All students now attend Sheffield and Rockwell. Each remaining school will have K–3, Rockwell will house 4–8 and Sheffield 9–12. The districts legally merged in 2011.
