John Keats was an English Romantic poet born in 1795 in London. He had a difficult childhood, losing both his parents to tuberculosis by age 15 and caring for his brother Thomas who also died of tuberculosis in 1818. Despite working as a surgeon, Keats dedicated himself to poetry and published his first collection in 1817. His most productive period was 1819 when he wrote his famous odes. Keats was diagnosed with tuberculosis in 1820 and died later that year at age 25. He emphasized beauty, the senses, and the concept of "negative capability" in his poetry.
