Harvey O'Connor (1897-1987) was a seminal radical journalist and labor historian who documented the lives of both rich and poor in America. His early work exposed the greed of the depression-era ""robber barons"" in books such as ""Mellon's Millions."" He was equally committed to documenting workers' struggle, and was sentenced for contempt for defying the McCarthyite witchhunt of the 1950s.
