Capitaine Didier Louis Marie Charles Lecour Grandmaison (18 May 1889 – 10 May 1917) was a World War I flying ace credited with five aerial victories.
[1][2] Lecour Grandmaison was born in Nantes, France on 18 May 1889.
After two victories, he was made a Chevalier of the Legion of Honor on 1 October 1916.
A cross-reference of French losses with German victory records shows that Lecour Grandmaison and his gunners were probably the 19th victims of German ace Heinrich Gontermann.
