Sách/BookAuthors: Rosen, Fred (2016)
Shortly after being elected president of the United States, James Garfield was shot by Charles Guiteau. But contrary to what is written in most history books, Garfield didn't linger and die. He survived. Alexander Graham Bell raced against time to invent the world's first metal detector to locate the bullet in Garfield's body so that doctors could safely operate.
