The Samuel Gompers Memorial is a bronze collection of statues in Washington, D.C., sited on a triangular park at the intersection of 11th Street, Massachusetts Avenue, and N Street NW. Gompers was an English-born American who grew up working in cigar factories, where he witnessed the long hours and dangerous conditions people experienced in factory jobs. He helped with growing the Cigar Makers' International Union, and a few years later, founded the American Federation of Labor (AFL). The number of members rose from 50,000 to 3,000,000 during his time as president of the union. He was not only successful in expanding the power of the labor movement, but also increased its prestige.

Robert Ingersoll Aitken was an American sculptor. Perhaps his most famous work is the West Pediment of the United States Supreme Court Building.
