In 1916, construction began on the Cooper Branch of the Camden Free Public Library, completely funded by Eldridge Johnson and donated to the city of Camden, and two years later, the library was completed. The library was constructed with the highest quality materials, and even had a mosaic frieze that depicts “America” personified and receiving gifts from the rest of the world. The mosaic frieze was designed by D’Ascenzo Studios of Philadelphia in 1916. The bronze statues were designed by British sculptor Sir George Frampton and Philadelphia sculptor Albert Laessle.

The city of Camden was so grateful to Mr. Johnson that the name of the park was changed from Cooper Park to Eldridge R. Johnson Park in 1920. Over the years, Johnson kept constructing in the park, adding wading pools, a large fountain, statues of animals, including one of Peter Pan for the benefit of the city’s children.
