Fédora is a play by the French author Victorien Sardou. The first production in 1882 starred Sarah Bernhardt in the title role of Princess Fédora Romazov. She wore a soft felt hat in that role which was soon a popular fashion for women; the hat became known as a Fedora.
The play was turned into an opera, Fedora, by Umberto Giordano in 1898. In 1916 it was adapted into the Hungarian film White Nights, directed by Alexander Korda.
