In the novel Babel-17 the protagonist Rydra Wong is both a space captain and a poet. I have seen it asserted that Wong's poems are to some extent based on those of Marilyn Hacker.
Hacker was married to Samuel R. Delany when Delaney wrote Babel-17 and they edited Quark: A Quarterly of Speculative Fiction (4 issues; 1970–71) together. Hacker has been considers a member of the "New Formalist" school of poetry. She has won the National Book Award for Poetry, a Lambda Literary Award, The Nation's Lenore Marshall Poetry Prize, 1996 Poets' Prize, the 2001 Audre Lorde Award, and an Award in Literature from the American Academy of Arts and Letters in 2004. In 2013, she was inducted into the New York Writers Hall of Fame.
I am looking for any or all of: statements by Delaney or Hacker that Wong's verse is based on Hacker's work (or that it was not); published literary analysis comparing the two, or analysis by a poster here.
