Uh. Carnegie was...quite rich. He and Rockefeller got into a race (after JP Morgan passed away) to see who could give away all of their money the fastest. Unfortunately, Carnegie lost, because he died before Rockefeller, but he loved libraries and education, so Carnegie Mellon University, Carnegie Hall, many, many libraries, and other facilities were all funded by him.

...Basically, anything that's branded as "Carnegie" is probably based off his money.
