Ralph Waldo Emerson
Ralph Waldo Emerson was an American essayist, lecturer, philosopher, and poet who led the transcendentalist movement of the mid-19th century. Emerson wrote on a number of subjects, never espousing fixed philosophical tenets but developing certain ideas such as individuality, freedom, the ability for humankind to realize almost anything, and the relationship between the soul and the surrounding world. His most famous work includes the essays 'Self-Reliance' and 'Nature.' He was a mentor and friend to Henry David Thoreau.
