The Delegation for the Adoption of an International Auxiliary Language was founded on 7 January 1901 on Leau's initiative.[2] He co-wrote with Prof. Louis Couturat the monumental Histoire de la Langue Universelle (1903)[3] and its supplement Les Nouvelles Langues Internationales (1907).[4]
Leau studied at the École normal supérieure in Paris and received his doctorate there in April 1897.[5] Later he was a professor at the University of Nancy . There he was Dean of the Faculté des Sciences from 1931–34. In his dissertation, Leau examined, among other things, the iteration behavior of holomorphic functions in the environment of a rationally indifferent fixed point. His results are known today under the name (Leau-Fatou) Flower Theorem . They play an important role in the complex dynamics.
