Samuel Johnson (1709–1784) was an influential English writer, poet, essayist, moralist, and lexicographer, best known for compiling A Dictionary of the English Language (1755), one of the most important dictionaries in the history of the English language. Born in Lichfield, Staffordshire, England, Johnson studied briefly at Pembroke College, Oxford, but had to leave due to financial difficulties. Despite this, he became a prominent figure in literary circles in London. He wrote essays, poems, and biographies, and was known for his sharp wit and moral insight. His major works include The Lives of the Poets, the novel Rasselas, and numerous essays for publications like The Rambler. Plagued by health issues and depression throughout his life, Johnson nevertheless left a lasting impact on English literature. He was also the subject of one of the most famous biographies ever written: The Life of Samuel Johnson by James Boswell, which helped cement his legacy.
