Both.
Well Robeson was rewarded, but those awards were taken away by the US govt, only reinstated after his death.
People go on about the injustices handed out to Ali, Mandella and Rubin 'Hurricane' Carter. But they were popular causes.
Yeah yeah, songs have been written about those fellas as well.
Robeson did die poor, in a manner of speaking. The McCarthyists put him out of business. The greatest black singer of the 20th century has a relatively modest following.
Btw, Robeson played football as well - american football has its roots in rugby football - so in a way he is one of us. Those records were also stripped but I understand they have since been reinstated thanks to some determined people.
