The Order of Daedalians is a fraternal and professional order of American military pilots. The namesake of the order is Daedalus who according to Greek mythology was the first person to achieve heavier-than-air flight.
The idea of a fraternal organization for World War I aviators was first expressed by Brig. Gen. Billy Mitchell. His stated purpose of the order was to "... perpetuate the spirit of patriotism, the love of country, the memories, sad and pleasant, of our service during that period (World War I) and to further cement the ties of comradeship which bound us together in that critical hour of our nation's need....". Lt. Harold George was in the audience to hear Gen. Mitchell speak, and helped to formally organize the Order of Daedalians 13 years later, on March 26, 1934, at Maxwell Field in Alabama. The headquarters of the Order moved to Kelly AFB, Texas, in 1954. The current national headquarters is at Joint Base San Antonio (formerly Randolph AFB), Texas.
Virtually all of the more than 14,000 American World War I aviators who were commissioned officers and rated as military pilots no later than the Armistice, on November 11, 1918, have Founder Memberships in the Order, even though some did not participate in the Order during their lifetimes. At first, active membership was open only to Founder Members and their descendants, called Hereditary Members. Membership was further divided into two categories: Active, for commissioned officers, and Associate, for those who met membership requirements, but were not commissioned in the Regular Army.
In the early 1950s, the Order created Named Memberships for current or former military pilots of heavier-than-air powered aircraft. This expansion ensured a new source of members for the Order. Later changes allowed female commissioned pilots to join. In 2001 membership criteria were changed to authorize memberships for ex-commissioned officers, whether or not they retired, and for all Flight officers and warrant officers who held ratings as military pilots of heavier-than-air powered aircraft. In 2002 membership criteria were again changed to authorize memberships for WASPs.
