But “Selma” and “Saigon” don’t just represent headlines to be pushed aside on the way to the museum. They point toward the turmoil that preoccupied the poetry of Hayden and many of his contemporaries.

“Monet’s ‘Waterlilies’” was published in a 1970 collection called “Words in the Mourning Time.” The title poem is an anguished response to the assassinations of Robert F. Kennedy and the Rev. Dr. Martin Luther King Jr., and to the deepening quagmire in Vietnam. Another poem in the volume is a long elegy for Malcolm X. Throughout his career (he died in 1980, at 66), Hayden returned frequently to the struggles and tragedies of Black Americans, including his own family.

Born in Detroit in 1913, Hayden, the first Black American to hold the office now known as poet laureate of the United States, was part of a generation of poets — Gwendolyn Brooks, Dudley Randall, Margaret Danner and others — who came of age between the Harlem Renaissance of the 1920s and the Black Arts movement of the ’60s.

A poet of modernist sensibilities and moderate temperament, he didn’t adopt the revolutionary rhetoric of the times, and was criticized by some of his more radical peers for the quietness of his voice and the formality of his diction.

But his contemplative style makes room for passion.
