Nate Smith was a 1960’s civil rights activist in Pittsburgh who is best remembered for his work serving African American labor workers. He used his own body to stop bulldozers working on the U.S. Steel Tower and the Three Rivers Stadium because there were no blacks on the job. Smith’s presence was powerful. He led thousands of marchers in Pittsburgh during the black labor union protests. His efforts with U.S. Steel Tower and Three Rivers led to Mayor Joe Barr and Mayor Pete Flaherty cutting a deal with Smith’s Black Construction Coalition to hire 1,250 blacks into the construction unions over the next four years.
