At Lancaster High School in 1958, student Robert Heft created the design for the fifty star flag as a history class project. Expecting Alaska to gain statehood and Hawaii to follow, he remade an old 48-star flag by replacing the blue field and adding fifty stars with white adhesive. After Heft received a B- on the project, his teacher, Stanley Pratt, said the grade would be raised if Heft submitted the design to their congressman, Walter Moeller. Moeller forwarded it to the chairman of the Congressional Flag Design Committee, who approved of it, and President Dwight D. Eisenhower made it the official American flag in 1960. It became the only flag in American history to fly over the White House for more than five administrations.
