The memorial is dedicated to Dr. Benjamin F. Stephenson, a surgeon and Civil War veteran who founded the Grand Army of the Republic in 1866. Stephenson organized the first GAR post in Decatur, Illinois, on the 6th of April 1866, and wrote the organization's constitution and motto.
The memorial stands at Indiana Plaza in the Penn Quarter neighborhood of Washington, D.C., at the intersection of 7th Street, Indiana Avenue, and Pennsylvania Avenue NW. It is across the street from the Archives Metro station and is maintained by the National Park Service.
The bronze figures were sculpted by J. Massey Rhind, a Scottish-American sculptor who was born in 1860 and immigrated to the United States in 1889. He was known at the time as one of the country's best architectural sculptors, noted for the Soldiers and Sailors Monument in Syracuse, New York.
The memorial was formally dedicated at 2:30 pm on the 3rd of July, 1909. Attendees included President William Howard Taft, Senator William Warner, and hundreds of Union veterans, many wearing their military uniforms.
The memorial features a triangular granite shaft 25 feet tall on a 2-foot concrete base, with a bronze relief on each of its three faces representing Fraternity, Charity, and Loyalty. A bronze bust of Stephenson in military uniform is mounted below the Fraternity relief. Inscriptions include dates of the Civil War and the founding of the GAR.
The GAR raised $35,000 from its members, led by General Charles Partridge and the National Tribune. Congress appropriated an additional $10,000 on the 4th of March, 1907, bringing the total available funding to $45,000.
