Once a professional basketball player, Stephen Dunn (b. 1939) is currently the Distinguished Professor of Creative Writing at Richard Stockton College. His poetry collection, Different Hours, won the Pulitzer Prize for Poetry in 2001. Additional biographical information may be found here:
The poet reveals in his notes that Mrs. Cavendish is a character in a series of poems that he has composed and will be a character in more. It is not immediately apparent if Mrs. Cavendish is based on someone real or springs entirely from the imagination of the poet--I lean toward the latter.
Mr. Dunn also reveals in his notes that he is not yet sure whom the narrator of this narrative poem is. It may turn out to be, but is not necessarily, the poet. I believe that the narrator may turn out to be Mrs. Cavendish's conscience or her more sensible inner monologue--she could certainly use one.
