Édouard Blau
Édouard Blau (30 May 1836 – 7 January 1906) was a French dramatist and opera librettist. He was a cousin of Alfred Blau, another librettist of the same period.

Going to Paris at the age of 20 he worked at the Assistance Publique but from 1870 concentrated on theatrical writing. For his libretti he collaborated with Louis Gallet, Alfred Blau, Camille du Locle and Louis de Gramont.
