Marjorie Allen Seiffert (February 15, 1885 – January 1, 1970) was an American poet and winner of the 1919 Levinson Prize for Poetry.
She used several pseudonyms over the course of her career, including Angela Cypher for some of her lighter verse and Elijah Hay for poems she wrote as part of the Spectrist hoax.
Around this time, she created a pseudonym, 'Angela Cypher', under which she wrote a form of light verse that gave her latitude for barbed observations about women's lives.
[1] She had been invited in on the hoax by Bynner and Ficke, who felt they needed to broaden the circle of poets producing in the Spectrist style.
[2] In the aftermath, a number of critics who had earlier preferred Hay's verse to that of Morgan and Knish reversed their opinions on discovering the poet was a woman, and Hay/Seiffert's role in the Spectra affair has generally been diminished in subsequent accounts.
