Serving over 1000 students from grades nine to twelve, Denfeld High School has become a West Duluth landmark.

Denfeld was instrumental in the creation of a two-year program to train teachers which eventually grew to become the University of Minnesota Duluth.

Sullivan designed the H-shaped English Gothic style building which features medieval carvings by Duluth master stone carver George Thrana.

He carved for 40 years in sandstone, granite, marble and limestone and his work is featured on many Duluth buildings including the Lyceum Theater, Old Central High School, Glensheen, the Board of Trade Building, St. Louis County Courthouse and the St. Louis County Jail.

Its face was designed by Carl Shroer, a teacher at Central High School, and was completed by Denfeld students who welded together four sections cast in aluminum by the Duluth Brassworks Company.

Three options were proposed: The Duluth School District ultimately chose a modified version of the Red Plan, leaving Denfeld open and adding approximately half of the Central population.
