Miguel Mihura was born in Madrid in 1905. His father was an actor and theatrical producer. When he was in his twenties, he wrote his best-known comedy, Tres sombreros de copa, but its humour was not appreciated by the conservative pre-war Spanish society. Tres sombreros de copa was not staged until 1952, achieving a great success.
Mihura also wrote several screenplays in Spanish films during the second world war . Most of them were cut by the censors and some do not exist. One of his greatest contributions was in Welcome Mr. Marshall! (1953).
