One of the most enduring monuments to Dr. Pepper's zeal and generosity is the Free Library of Philadelphia. In 1889 his uncle, George S. Pepper, bequeathed the sum of one hundred and fifty thousand dollars "to the trustees of such Free Library which may be established in the city of Philadelphia." From the beginning Dr. Pepper took a warm interest in the Free Library movement. It was under his leadership that the library was organized, and he was made the first president of its board of trustees. Speaking of his activity in this direction, the librarian, Mr. John Thomson, said: "No detail was too small for his personal attention.
