Amazingly, Cyrano de Bergerac was banned from the United States for 15 years because a federal judge decided that Edmond Rostand had plagiarized it from a Chicago real estate developer.

The developer, Samuel Gross, had written The Merchant Prince of Cornville in 1896 and had 250 copies printed privately. In 1900 he brought suit in U.S. district court, and Judge C.C. Kohlsaat ruled that Rostand was “a plagiarist and by inference a perjurer” for “obviously” borrowing from Cornville and then denying he’d ever heard of it. The judge issued a perpetual injunction against the production of Cyrano in the United States.

So was Rostand guilty? Decide for yourself — here’s a sample of the work he “stole”:

Violet: I thought I heard some one speak, but not from underground, for he’s not a goblin; nor yet from the sky, for he’s not an angel; nor yet from the earth, for no dreadful man is near. Why, what is that in the sky? ‘Tis last eve’s moon, that will not to her couch by day. To rest! pale planet. Oh gentle moon, where is thy blush? Thou art dismantled by the roseate sun. Alack! what divine dramas are there in the skies!

The ban was eventually overturned: In 1915 Gross failed to stop an operatic production of Cyrano, and in 1923 the original play was revived successfully. I’m not really sure what happened to The Merchant Prince of Cornville.
