Robert Lowell was a prominent American poet, considered a foundational figure in the confessional poetry movement. Born into a Boston Brahmin family, his early work was formal and traditional, but he later developed a more personal and intense style. His 1959 book, 'Life Studies', won the National Book Award and is often cited as one of the most influential American books of poetry of the 20th century. Throughout his life, he was a dedicated teacher and a vocal political activist, leaving an indelible mark on modern literature.
