An unidentified black soldier of the American Lincoln Brigade serves in the Spanish civil war.
The soldier is one of more than 90 African-Americans who volunteered to serve in Spain against the fascists during the civil war in Spain.
Many of the people who volunteered for the Abraham Lincoln Brigade were official members of the Communist Party USA or affiliated with other socialist and anarchist organizations like the Industrial Workers of The World (IWW or Wobblies).
It was also the first time an African-American commanded an American military unit. Oliver Law, a black communist and labor organizer, commanded the American Lincoln Brigade for four days in the Spanish Civil War.
In 2009, Spanish authorities attempted to put a name to the photo so they can present it to Barack Obama during his visit to Spain and to locate his family. Two possible candidates have emerged: Milton Herndon, whose brother Angelo won a famous supreme court case against a sentence for “incitement to insurrection”, and aviator Paul Williams.
