Walt Whitman (1819-1892) was an influential American poet, essayist, and journalist, renowned for his groundbreaking work "Leaves of Grass," which celebrated democracy, nature, love, and the human spirit. Embracing a free verse style and a bold, candor-filled approach, Whitman broke traditional boundaries of poetry, becoming a pivotal figure in American literature. Born in Long Island, New York, and raised in Brooklyn, his diverse experiences—from teaching and journalism to volunteering as a nurse during the Civil War—influenced his expansive, humanistic vision. Often dubbed the "Father of Free Verse," Whitman's legacy endures, inspiring generations of poets and readers globally.
