GBN Serves Most of Northbrook, some unincorporated portions of Cook County, and a small section of Glenview. History In 1930, Northbrook opened Northbrook High School to serve its residents. But as Northbrook grew due to American suburbanization, more space to accommodate students was needed, warranting its closure and the construction of a new high school. Founding Glenbrook North High School opened its doors in the fall of 1953 as Glenbrook High School, with its name being a combination of "Northbrook" and "Glenview". After the opening of Glenbrook South High School in Glenview, the school was renamed to Glenbrook North. Subsequently, the two schools formed Glenbrook High School District 225. Glenbrook North has grown fourfold in the size of its student body since its founding. In 1979, the school opened the Sheely Center for the Performing Arts, and in 1990, a fieldhouse was dedicated. In the spring of 1996, a three-year renovation and construction project involving the science facilities and the "A" wing was built. A second swimming pool was built in 2000 to accommodate the burgeoning growth in aquatics. A successful referendum in 2006 enabled the creation of the two-story classroom "F" wing, state of the art Fitness Center, complete renovation and additions to the Music Area, and a sun-filled main entrance, which were completed in 2009. Throughout the years, Glenbrook North High School has received state and national recognition for its academic excellence. In the late 1950s, when Glenbrook was less than 10 years old, it was named one of the top 44 high schools in the country by a survey in a national magazine. In 1984, GBN was named one of only four high schools in the state of Illinois to receive the United States Office of Education Excellence in Education Award from President Ronald Reagan. In 2008, GBN was selected again for the nation's top distinction as a Blue Ribbon School. John Hughes films John Hughes was an alumnus who used the school in
