Prior to World War II, the award was administered by the International League of Aviators ("Ligue Internationale des Aviateurs"), an organization founded by Harmon to serve as "an agent for Peace and National security." The League became defunct during the war and Harmon's death on June 25, 1945 in Cannes, France put the awards in turmoil. Harmon left $55,000 of his estate to continue funding the award in "perpetuity," but Harmon's relatives challenged the bequest. Ultimately, a trust fund of $48,431 was created in 1948.
