At the beginning of the 20th century, the need for an international language was being thought about by many personalities, especially scientists and philosophers. This period goes along with a flowering of new international language projects. The math expert Leopold Leau creted the Delegation for the adoption of an international auxiliary language on January 17, 1901 with the support of many scientists. In 1906, the Delegation had received the support of more than 1,200 members of universities from different countries and more than 300 scientific societies.
