Edward Estlin Cummings was born in Cambridge, Massachusetts, on October 14, 1894. He began writing poems as early as 1904 and studied Latin and Greek at the Cambridge Latin High School.
In 1917, Cummings published an early selection of poems in the anthology Eight Harvard Poets. The same year, Cummings left the United States for France as a volunteer ambulance driver in World War I. Five months after his assignment, however, he and a friend were interned in a prison camp by the French authorities on suspicion of espionage (an experience recounted in his novel, The Enormous Room) for his outspoken anti-war convictions.
After the war, he settled into a life divided between his lifetime summer home, Joy Farm in New Hampshire, and Greenwich Village, with frequent visits to Paris. He also traveled throughout Europe, meeting poets and artists, including Pablo Picasso, whose work he particularly admired.
In his work, Cummings experimented radically with form, punctuation, spelling, and syntax, abandoning traditional techniques and structures to create a new, highly idiosyncratic means of poetic expression. Later in his career, he was often criticized for settling into his signature style and not pressing his work toward further evolution. Nevertheless, he attained great popularity, especially among young readers, for the simplicity of his language, his playful mode and his attention to subjects such as war and sex.
The poet and critic Randall Jarrell once noted that Cummings is "one of the most individual poets who ever lived—and, though it sometimes seems so, it is not just his vices and exaggerations, the defects of his qualities, that make a writer popular. But, primarily, Mr. Cummings's poems are loved because they are full of sentimentally, of sex, of more or less improper jokes, of elementary lyric insistence."
During his lifetime, Cummings received a number of honors, including an Academy of American Poets Fellowship, two Guggenheim Fellowships, the Charles Eliot Norton Professorship at Harvard, the Bollingen Prize in Poetry in 1958, and a Ford Foundation grant.
At the time of his death, September 3, 1962, he was the second most widely read poet in the United States, after Robert Frost. He is buried in Forest Hills Cemetery in Boston, Massachusetts.
