Ralph Waldo Emerson

(May 25, 1803  – April 27, 1882) was an American philosopher, lecturer, essayist, and poet, best remembered for leading the Transcendentalist movement of the mid-19th century. He was seen as a champion of individualism and a prescient critic of the countervailing pressures of society, and he disseminated his thought through dozens of published essays and more than 1,500 public lectures across the United States.
