Like many North Americans, I don’t read a lot of poetry, but I do have an appreciation for the form. I also kind of like championing an underdog, so I’m always interested in sharing a good poetry related story when I see one, and the United States Postal Service has just that in their 2012 stamp program. Next year, the USPS will release a series of ten stamps called Twentieth Century Poets. From the USPS website preview:
The poets included make a wonderful reading list for anyone looking for a good overview of the great names in 20th Century American poetry.

Joseph Brodsky (M): Russian poet Brodsky was expelled by the Soviet Union in the 1970s and went to the US. Published originally in Russia before his exile, Brodsky studied under Russian great Anna Akhmatova. Brodsky was the first US Poet Laureate and a winner of the Nobel Prize in Literature.
Gwendolyn Brooks (M): A prolific poet of more than 20 books, and the first African American author to be awarded a Pulitzer Prize. According to The Poetry Foundation, “many of Brooks’s works display a political consciousness, especially those from the 1960s and later, with several of her poems reflecting the civil rights activism of that period” and they note that “Brooks once described her style as “folksy narrative,” but she varied her forms, using free verse, sonnets, and other models.”

Robert Hayden (M): Born and raised in Detroit, Hayden studied under British poet W.H. Auden at the University of Michigan. Hayden wrote “formal, elegant poems about the black historical experience” that were grounded in extensive study as well as personal experience.
Denise Levertov (M): British born American poet Levertov is the only of these poets I haven’t heard of, and as a result, perhaps the one I’ll explore first. A poet who was both political and religious, she was the poetry editor for the Nation magazine during the 1960s and published over 20 books, and won several major prizes.

Theodore Roethke (M): During my undergrad, I took a class called 20th Century Poetry and have a distinct memory of studying and loving a poem called The Far Field by Roethke. The Wikipedia entry for Roethke notes that he was a poet known for his “rhythm, rhyming, and natural imagery

William Carlos Williams (M): A doctor as well as a poet, Williams was considered a modernist who was “known as an experimenter, an innovator, a revolutionary figure in American poetry.” Like Sylvia Plath, he was posthumously awarded the Pulitzer Prize and he continues to be recognized by the Poetry Society through annual award in his name
