In the 1940s, Bethune used her influence and friendship with Eleanor Roosevelt to secure luxury travel buses for Eddie Durham's All-Star Girls Orchestra, an African-American, all-women's swing band. Bethune was the only black woman present at the founding of the United Nations in San Francisco in 1945, representing the NAACP with W. E. B. Du Bois and Walter White. In 1949, she became the first woman to receive the National Order of Honour and Merit, Haiti's highest award. She served as the U.S. emissary to the induction of President William V.S. Tubman of Liberia in 1949. She also has had essays written about her. She also served as an adviser to five of the presidents of the United States. Calvin Coolidge and Franklin D.
