Reading material concerning Eugene Debs

[Os Cangaceiros]

Does anyone know if there are any good biographies of him?

I just ask because he is one of my favorite historical figures, and I'd like to know more about his life.

"Eugene V Debs: Citizen and socialist" by Nick Salvatore is basically the definitive biography on the guy.
