Switching careers, he then worked for the Minnesota Department of Natural Resources wildlife section in the 1970s and later as a wildlife technician at the Sand Lake National Wildlife Refuge in South Dakota. He is now retired. In 1972 he helped found the Minnesota Writers’ Publishing House (MWPH), a publishing cooperative, backed by Robert and Carol Bly, established to highlight Midwestern literature. Foreign many years, Hennen operated the MWPH press in his garage.
Hennen belongs to a cohort of Minnesota poets strongly influenced by Robert Bly, Louis Jenkins and Bill Holm (poet).
He is a poet of the landscape—in the words of Bly, his poems have an “ability to bring immense amounts of space, often uninhabited space, into his mind and so into the whole poem.” This yearning to describe the feeling of space has led to his extensive use of the prose poem, where he has found room to “move freely within the rectangular tract of the paragraph.” Hennen’s most recent book, Darkness Sticks to Everything: Collected and New Poems was published in 2013 by Copper Canyon Press. Novelist and poet Jim Harrison introduces the volume, calling Hennen “a genius of the common touch.” Dana Jennings writes in the New York Times, "lieutenant"s hard to believe that this American master - and I don"t use those words lightly - has been hidden right under our noses for decades.".
