Who was William Waldorf Astor?

A fictional character in a fictional chicken soup.

The content of Chicken Soup is as follows: William Waldorf Astor stayed in a hotel overnight. The hotel was full, and George Burt, the waiter at the hotel, said: If you don't mind, you can sleep in my room.

The next day, William Waldorf Astor said to the waiter: Thank you very much, I will build you a hotel of your own in the future!

Many years later, William Waldorf Astor kept his promise, and the waiter became the first general manager of the famous XXX Hotel.

This story is false. William Waldorf Astor was probably based on a certain rich man.
