William Theodore Peters (1862 – 1905 in Paris)[1][2] was an American poet and actor.
Associated with 1890s decadence, he was a friend of Ernest Dowson, who dedicated a poem to him, "To William Theodore Peters on His Renaissance Cloak".
In October 1892, he commissioned Dowson to write the play that would ultimately become the Pierrot of the Minute, for him to act in.
This was included in Peters' book of verse, Posies Out of Rings and Other Conceits, a "quaint little salmon pink volume", which was published by John Lane and the Bodley Head in 1896.
The work was performed at the Théâtre d'Application, 18 rue St. Lazare, on May 8, 1894, with Peters playing the part of the troubadour Betrand de Roaix.
