The first McDonald's was built in Des Plaines Illinois, by the McDonald brothers (Yes there last names were actually McDonald) Mack and Richard. Later the franchise was expanded by a man named Kroc who wanted to expand the franchise nationwide. The Mcdonald brothers didn't really approve but he convinced them that he would take all the blame if it failed. But it didn't and McDonald's is now one of the most popular fast food chains in the country.
