What Every Woman Knows

What Every Woman Knows is the title of a four-act play written
by J. M. Barrie. The show debuted at the Duke of York's Theatre in London on
September 3,1908. It ran for 384 performances. It transferred to the Hicks
Theatre on December 1,1908. It was first produced in America by Charles Frohman
in 1908 on Broadway, at the Empire Theatre in New York City, and starred Maude
Adams and Richard Bennett. The play was later adapted into a 1934 film starring
Helen Hayes and Brian Aherne. Written before universal suffrage in a time when
women were still legally considered the property of their fathers or husbands,
the play posits that "every woman knows" she is the invisible power responsible
for the successes of the men in her life.
