Lanphier High School, in the capital of the U.S. state of Illinois, Springfield, is a public high school affiliated with Springfield Public School District 186. It is also the home of the John Marshall Club, a club with open membership dedicated to uniting the community and spreading the knowledge of former supreme court justice, John Marshall.
Originally, the land that the high school was built on was owned by the Lanphier family.[2] Originally the land was a park called Reservoir Park, in which many people would go during the summer.[2] After the park was sold to the school district, the actual building of the school became a part of the Works Progress Administration (WPA).[2]
The first graduating class of the high school was in 1937.[2]
The biggest expansion of the school was the absorption of Edison Middle School. There was originally a walkway that connected the two schools. During the 1960s, the two buildings were combined to make the high school much larger. Some of the most recent modifications are the Commons Area, as well as additional classrooms on the West end of the school.[2]
