75 Years of Excellence

Glenbrook High School District 225 is celebrating 75 Years of Excellence through our alumni and faculty.

It was on April 12, 1947, when voters in Northfield Township approved the establishment of District 225. The approval came after District 29 in Northfield voted to remain a part of New Trier High School District 203. Prior to District 225’s establishment students in the community were attending other area high schools such as Deerfield-Shields in Highland Park, New Trier in Winnetka, Niles, Maine High School, Carl Schurz, and Northbrook High School.

In honor of the 75th anniversary, District 225 is asking its alumni to share stories about their time in District 225. Please submit a video and or image with a quote about a favorite memory, an experience that impacted your life today, etc. You can find stories of the District’s alumni throughout the school year here and on social media.

District 225 First Superintendent Dr. Norman E. Watson said, “We do not wish, in the Northfield Township High School, to copy any of our neighbors entirely. We are surrounded by many superior high schools which constitute a challenge to our planning. At the same time, however, we do not deem it wise to copy a plan. We should be grateful for those splendid ideas developed in all of them, but we do hope on our own initiative to develop a school which will best serve the people of Northfield Township.”

Glenbrook South’s first principal Dr. Sydney Salt said, “Glenbrook South is more than the name for an 80-acre cornfield I visited in early 1961. It means ‘community team’ in my reflection. Students, parents, elected officials, citizens with or without children, educators, and all others - yes even our planned rivals at Glenbrook North - were an open-minded team, helpful in defining the ‘School of the Future.’”
