who where the social writers in the progressive era in the united states?

Answer 1

It looks like you have a lot of papers to write, Stevo, judging by the number of essay questions you are dumping into the history category here. If you are planning to do any of the work yourself you might start by googling Upton Sinclair and Jane Addams to see where they lead.

Answer 2

Jane Adams, Henry Ford, Jack London, John D. Rockefeller Jr., there were many, just google Social writers + Progressive Era. You should come up with something.
