Blanche Marie Louise Oelrichs (October 1, 1890 – November 5, 1950) was an American poet, playwright and theatre actress. Oelrichs first used the masculine nom de plume Michael Strange to publish her poetry in order to distance her society reputation from its sometimes erotic content, but it soon became the name under which she presented herself for the remainder of her life. She was married to John Barrymore and was the mother of Diana Barrymore.
