If Ray Kroc's last name wasn't McDonald, why is it called McDonald's and not Kroc's?

McDonalds was named after the brothers who bought 9 Burger stores in the early 1950.s. Ray Kroc joined them in 1954 (at that time McDonalds was struggling) and changed the company into a Franchise.

Ray Kroc started out as a salesman for milkshake machines used in fast food restaurants. He delivered to this fast-food place in San Bernardino, CA, run by two brothers named McDonalds. He loved the whole idea of the place and he tried to convince the bros to expand to a chain, but they were older and ready to retire. So he bought the place from them, and as they say, the rest is history.

And I agree with the first answerer--calling it Krocs wouldn't have been a good idea. But then it did work for shoes, didn't it? 8^)

Ray Kroc purchased the chain that was originally created by Richard and Maurice McDonald.

Would have gone out of business in about a year.

The restaurant, started by the McDonald brothers, was already in existence when Kroc bought it.

He had friends with the last name McDonalds who owned the burger joint actually. He bought the company from them but kept the name. I believe it was two brothers. I remember watching a documentary about it.

He bought it off them.
