Walt Whitman, born Walter Whitman on May 31, 1819, in West Hills, Long Island, New York, is celebrated as one of America’s most influential poets and a pivotal figure in the transition from transcendentalism to modernism. He passed away on March 26, 1892, in Camden, New Jersey. Throughout his life, Whitman’s work and philosophy significantly shaped American literature and poetry, earning him a lasting legacy as the "father of free verse."

Whitman grew up in a large family, receiving a modest education that ended around the age of 11. He worked various jobs, including as a printer and a teacher, which exposed him to the literary world and fostered his passion for writing. His early life experiences in a rapidly changing America deeply influenced his worldview and poetic themes, particularly his commitment to democracy and the human spirit.

His literary career began in earnest with the self-publishing of "Leaves of Grass" in 1855, a groundbreaking collection that celebrated individuality, nature, and human connection. This work, which he continued to revise and expand throughout his life, marked a departure from traditional poetic forms and embraced free verse. Other notable works include "Song of Myself," "Crossing Brooklyn Ferry," and "Drum-Taps," the latter reflecting his experiences and observations during the Civil War.

In his personal life, Whitman was known for his unconventional views on sexuality and relationships. He never married but had many close friendships, and his poetry often explored themes of love and camaraderie. Despite facing criticism and controversy for his frank portrayals of the human experience, Whitman's work has endured, influencing countless writers and poets and cementing his status as a literary icon. His belief in the interconnectedness of all people continues to resonate, making him a vital figure in American literature.
