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