abstract:Stephen Decatur High School, located in Decatur, Illinois, existed from 1911 to 2000. The original Stephen Decatur High School was simply known as Decatur High School until 1957, when the city's only high school was joined by Lakeview High School (absorbed by consolidation), and MacArthur and Eisenhower High Schools (newly constructed) to accommodate the student population that was exploding as a result of the post World War 2 "baby boom".
