The current United States flag was designed by a high school student

Robert Heft, born in Saginaw, Michigan, was the designer of the 50-star flag.
He designed the current U.S. flag in 1958 when he was 17 years-old for a class project. He unstitched the blue field from a family 48-star flag, sewed in a new field, and used iron-on white fabric to add 100 hand-cut stars, 50 on each side of the blue canton.

He originally received a B- for the project. After discussing the grade with his high school teacher, Stanley Pratt, it was agreed that if the flag was accepted by Congress, the grade would be reconsidered. Heft's flag design was chosen and adopted by presidential proclamation after Alaska and before Hawaii was admitted into the union in 1959. According to Heft, his teacher did keep to their agreement and changed his grade to an A for the project. Go to LINK to see the video.
