Alexander Graham Bell invented many things, the most famous is the telephone, except he didn't invent the 'phone. The telephone was invented by an Italian called Innocenzo Manzetti, Bell just gets the credit.
Bell did invent the metal detector. US president James Garfield was shot by an assassin, and Bell built an instrument to find the bullet. It worked perfectly, but couldn't find te bullet because the dying president was lying on a bed with metal bedsprings.
