Ignatius Loyola Donnelly (November 3, 1831 – January 1, 1901) was a U.S. Congressman, populist writer, and amateur scientist. He is known primarily now for his theories concerning Atlantis, Catastrophism (especially the idea of an ancient impact event affecting ancient civilisations), and Shakespearean authorship, which many modern historians consider to be pseudoscience and pseudo history. Donnelly's work corresponds to the writings of late 19th and early 20th century figures such as Helena Blavatsky, Rudolf Steiner, and James Churchward. (Wikipedia)
