Blanche Marie Louise Oelrichs, who wrote under the name Michael Strange, was an American poet, playwright, and theater actress. 

With drawings provided by her second husband, actor John Barrymore, Strange published a book in 1921 titled Resurrecting Life. Her pseudonym was intended to separate her family from the erotic content of the volume and its connection to her affair from Barrymore, but instead, the vast popularity of the volume led to greater fame and notoriety, and her adaptation of the Strange name permanently.[1]

In 1921, Strange was among the first to join the Lucy Stone League, an organization that fought for women to preserve their maiden names after marriage.[2]

She was also an involved activist for women's suffrage. 

Starting in the summer of 1940 until her death, Strange was in a long-term relationship with Margaret Wise Brown, the author of many children's books. The relationship began as something of a mentoring one but became a romantic relationship, and they lived together at 10 Gracie Square beginning in 1943.[3]
