Dr. William Fisher was the first President of the International Orthodontic Congress (IOC). He was also the President of American Society of Orthodontists (ASO). The ASO was celebrating its 25th anniversary of its founding in 1901. At that time, the International Congress consisted of fifteen orthodontic societies.
"2nd International Orthodontic Congress" was held in 1931 in London, England. Dr. J.H. Badcock was the President of 2nd International Congress, in addition to helming the Presidency of European Orthodontic Society (EOS) and British Society for Study of Orthodontics (BSSO).
"3rd International Orthodontic Congress" was to be held in 1938 in Montreal, Canada. Due to the tensions of WWII and death of Dr. Fisher, the 3rd international congress did not take place in Montreal. For next three decades, due to Korean and Vietnam War, the organization of the Congress was further delayed. Eventually the 3rd IOC was held in 1973 in London. Dr. William J.
