Housed in the atrium of the US Patent and Trademark Office, this museum tells the history of the US patent. Step inside to see where the story started in 1917 in Memphis, Tennessee, when a wholesale grocer named Clarence Saunders invented and patented what he called 鈥榮elf-servicing鈥 stores, now commonly known as supermarkets.
Incidentally, Saunders went from rags to riches and almost back to rags again, but you鈥檒l have to visit the museum to get the rest of the story, along with displays depicting other famous and influential patents. It is about a third of a mile from the King St Metro station; take Diagonal Rd south to Dulany St.
