After graduating from Lowell University, he studied as a graduate student for one year under the guidance of famous literary theorists and critics of Louisiana State University, namely Collins Brooks and Robert Pan Warren. 1943 was imprisoned for five months for refusing to perform military service in World War II. 1944, Lowell published his first book of poetry, The Impossible Land, which described a world in crisis and his expectation of seeking spiritual liberation. 1946 published Lord Tired's Castle, which was well received and won the Pulitzer Prize for Poetry. 195 1 year, a long narrative poetry anthology "The Mill of Cabano Family" was published, which tells a Greek legend, but the background is New England in the United States. Since then, he has been teaching poetry at Boston University. His students include Sylvia Plath and anne sexton, who later became poets. During this period, Lowell was often troubled by schizophrenia and had to stay in the neurological rehabilitation center for a period of time. 1957 went to the west coast of the United States to recite poems. He was moved by Howl recited by allen ginsberg, a beat poet, and turned to walt whitman and william carlos williams's free verse style. Life Research, published in 1959 and awarded the National Book Award in 1960, reveals Lowell's inner pain and suffering, and marks a great change in Lowell's poetic style. This collection of poems made him an important representative of the confessional poetry school in the 1950s. In a group of free and blank poems, he expressed his life experience and psychological changes frankly and simply. In the famous poem Memories of West Street and Lepke, he recalled his frenzied youth and prison life from the calm 1950s. In the poem "Skunk Time", he used complex images to reflect the pain of alienation and self-help and liberation in despair. These autobiographical poems are full of real life experiences and plots, and the language is simple, cordial and touching, and their influence makes the so-called "confession poems" a temporary fashion.
Lowell participated in anti-war and democratic activities in the 1960s when he taught at Harvard University from 1963 to 1977. 1965 refused the invitation of President lyndon johnson's White House banquet to protest against American foreign policy. 1967 joined the ranks of opposing the Vietnam War and marched into the Pentagon.

The Old Glory (1965), a dramatic trilogy adapted from the stories of Hawthorne and Melville, makes a historical survey of American culture.
