Racine vs. Voltaire

When Louis Napoleon was in temporary exile in New York, he complied with the request of a young lady for his autograph in her album as follows:

“Le premier qui fut roi, fut un soldat heureux;
Qui sert bien son pays n’a pas besoin d’aïeux.

“Louis Napoléon Bonaparte.

“(Racine.)
“New York, 10 June, 1837.”

The Prince and future Emperor thus attributed to Racine a couplet which should have been credited to Voltaire.
