The Order of the Iron Key is a senior leadership honor society founded at Purdue University in 1910 and limited to ten members per year. From A University of Tradition: The Spirit of Purdue by the Purdue Reamer Club (West Lafayette: Purdue University Press, 2002): "New members are chosen by current members based on scholarship, positions held in student organizations, high ethical character, and the desire to lead on the Purdue campus anonymously... Funding comes from donations by the Purdue Alumni Association. Iron Key alumni, and other sources in the University and local community. Strictly nonpolitical in policy, Iron Key aims to be representative of the class and student body... It is the policy of the society to be secret so that no public announcement of membership is made until the close of the college year. The mission of the club... is to do good for the sake of goodness alone." (176-177)
