Walter Whitman was born in 1819 on Long Island, New York to parents with Quaker beliefs. He had eight siblings and was nicknamed "Walt." As a teenager, he worked as a printer but also enjoyed literature. In the 1850s, he began writing Leaves of Grass, a collection of poetry that explored unconventional themes like sexuality and death. Whitman spent his later years in Camden, New Jersey, where he died in 1892 after a long career as a poet known for breaking conventions.
