According to the club, its mission was: "To promote the general welfare of men and women of the Armed Forces of the United States and its Allies, and their families, by maintaining and offering club and lodging rooms"In 1919, Cornelia Barnes Rogers and Eleanor Butler Alexander-Roosevelt, wife of Theodore Roosevelt Jr., along with General John J. Pershing, founded The Soldiers' and Sailors' Club to accommodate servicemen returning from overseas duty in World War I.
With no U.S. government funding, supported solely by guest proceeds and the donations of private citizens, it has accommodated over 2.5 million men and women of the US military and their families.
One of the largest fundraisers for the club is the prestigious International Debutante Ball held biannually at the Waldorf-Astoria Hotel in New York City.
Since the early 1920s, the SSMAC Club has occupied two adjacent 19th century townhouses on Lexington Avenue between 36th and 37th Streets.
(Private rooms are dedicated to individual veterans, families and other donors having provided pictures, certificates, etc.
