Britannica: Biography of Emily Dickinson
Emily Dickinson, in full Emily Elizabeth Dickinson, (born December 10, 1830, Amherst, Massachusetts, U.S.—died May 15, 1886, Amherst), American lyric poet who lived in seclusion and commanded a singular brilliance of style and integrity of vision. With Walt Whitman, Dickinson is widely considered to be one of the two leading 19th-century American poets.
Only 10 of Emily Dickinson’s nearly 1,800 poems are known to have been published in her lifetime. Devoted to private pursuits, she sent hundreds of poems to friends and correspondents while apparently keeping the greater number to herself.
