Poet Philip Levine On "What Work Is."

The Pulitzer Prize-winning poet grew up in Detroit and worked in the factories as a young man. He's probably best known for his 1992 book of poems about the working class, "What Work Is," which won the National Book Award. He has several volumes of poetry as well as a memoir. His forthcoming book is called "Unselected Poems."

Natasha Trethewey was awarded the Pulitzer Prize for Native Guard, her most recent collection of poetry. The title refers to a regiment of African- American soldiers who fought for the Union in the Civil War.

Trethewey grew up the child of a racially mixed marriage in Mississippi. Her mother was murdered by her stepfather; these, along with the South and its singular ways, are recurring themes in her poetry.

Trethewey teaches creative writing at Emory University. Native Guard is her third collection.
