Ray Kroc, who held distribution rights to the five-pronged Multimixer, heard of a place called McDonald's that had eight of his mixers going at once.

He approached the McDonald brothers, Dick and Mac, about opening more restaurants. Imagine all the Multimixers he'd sell if there were more restaurants like the one run by the McDonalds.

And so Kroc opened the first of many McDonald's franchises to come - more than 30,000 restaurants in 119 countries serving 47 million people daily. Today the Des Plaines restaurant is a McDonald's museum. It houses, among other things, the Multimixer.
