in 1925. The Iron Ring originated from
H. E. T. Haultain, a mining engineering professor at the
University of Toronto. On 25 January 1922, Haultain proposed that engineers take an ethical oath. From 1922 to 1925, the structure that would administer the oaths, or "callings," was known as the Corporation of the Seven Wardens. The organization was named in honour of the first seven presidents of the Canadian Society for Civil Engineers. The text of the calling was written by English poet
Rudyard Kipling, at the request of Haultain. Haultain asked Kipling to author the calling partly because of Kipling's poem
The Sons of Martha, which paid tribute to an engineer. Kipling's calling sought to emphasize the responsibilities of an engineer, affirming their responsibility to "not henceforward suffer or pass, or be privy to the passing of, Bad Workmanship or Faulty Material." Kipling's calling also affirmed that an engineer must not compromise their work, in spite of external pressures; and was a call for professional unity between engineers. On the 25 April 1925, Haultain administered the first
Ritual of the Calling of an Engineer in the University Club in
Montreal. However, the initial batch of Iron Rings were actually produced by
World War I veterans at Christie Street Military Hospital in
Toronto. The Wardens originally considered expanding the ritual to the United States. However, they later ruled against expansion, fearing a loss of control over the ritual. Efforts to secure control of the ritual were made in 1935, when the obligation was copyrighted, and the Corporation of the Seven Wardens formally incorporated in 1938. ==Design==
