a picture of Henry David Thoreau https://en.wikipedia.org/wiki/File:Henry_ David_Thoreau_1862.jpeg Henry David Thoreau. WHO IS HE??? One naturalist that I really love learning more about is named Henry David Thoreau. He is known as an American writer, thinker, and naturalist. His main focus was exploring deeper interest in nature. He kept a journal whilst exploring a place called Walden Pond, and later created a book called, Walden . His words were extremely powerful, and he ended up being one of the most powerful voices for the natural environment ( Walden.org). The main thing that motivated him was nature. He believed that nature could soothe all people much like different religions. He spent 2 years at Walden Pond, and showed throughout his writing how transcendentalism can impact a human being. Transcendentalism teaches that divinity pervades all nature and humanity, and its members hold progressive views on feminism and communal living. Ralph Waldo Emerson and Henry Davi
