All Denver Public Schools started back to school this week, from elementary schools to high schools. Denver's oldest school, East High School, has educated Mile High residents for almost 150 years. The school opened in 1859 with 13 students in a log cabin. The current high school, a Denver Historic Landmark, opened its doors in 1925 near City Park. Famous alumni who graduated from East High include Don Cheadle, Pam Grier and Judy Collins. The East High Angels also captured some recent celebrity of their own by winning the state basketball championships in 2007.
