McDonald's

The previous song mentioned a farmer called "Old McDonald". Find out if he has something to do with the  McDonald's company. Have a look at its webpage www.mcdonalds.com and answer the following questions:

1. Who founded McDonald's?
2. When?
3. What did he do before founding his first restaurant?
4. When did he die?

Now think about a Spanish big company. Find out who his/her founder is and write about him/her (100 words max.)
