Did you know that a teenager designed the United States flag? Bob Heft was just 17 years old when he created the flag for a school project in 1958. Heft submitted his design to the White House and, after two years, got a personal call from President Dwight D. Eisenhower telling him that his design would become the flag of the United States. Ironically his teacher gave him a B- on the assignment but would later change his grade to an A.
