Evaluate the business and charitable contributions of andrew carnegie and john d. rockefeller

Both Carnegie and Rockefeller were the biggest businessmen and the riches in the 20th century. After all their great amount of profits garnered, both had individually decided to embark in a journey of charities. Carnegie had charity contributions that were made into school such as the Carnegie Institution, Tuskegee Instituion, and a lot more. He was dubbed as the patron saints of libraries and decided to set up more charitable foundations. Rockefeller on the other had a lot of charities and activities that gave away his excess money into charitable causes. He too had built schools by starting to build University of Chicago.

But with all their charitable and business contributions, I would say I like Carnegie more because it gave away of a lot of technologies we know of today and he is working on a principle he deeply believes in that after gaining your wealth you should contribute this wealth for the general welfare. However, Rockefeller too was great and focused his contributions on public service.
