It happened on September 1

On the 1st of September in 1906, a group of attorneys established the International Federation of Intellectual Property Attorneys. I am reasonably certain that there is no connection between the formation of this group of lawyers and the outbreak of World War 1 in June of 1914 though it should be noted that lawyers were involved in both instances. That could be merely a coincidence but in the times we live in one cannot be too careful.
