Ella Wheeler Wilcox (1850-1919) was an American author and poet. Her best-known work was Poems of Passion (1883), and her autobiography, The Worlds and I was published in 1918 shortly before her death. She started writing poetry at a very early age, and was well known as a poet in her own state by the time she graduated from high school. She married Robert Wilcox. Not long after their marriage, they both became interested in Theosophy, New Thought, and Spiritualism. She made efforts to teach occult things to the world. Her works, filled with positivism, were popular in the New Thought Movement and by 1915 her booklet, What I Know About New Thought had a distribution of 50,000 copies, according to its publisher, Elizabeth Towne.
