About the Author
The author and politician Ignatius Donnelly was born in Philadelphia on 3 November 1831. He was educated in the public schools of his native city, studied law, was admitted to the bar, and practiced. He went to Minnesota in 1857, was elected lieutenant governor in 1859, and again in 1861, and was then elected to Congress as a Republican, serving from 7 December 1863 until 3 March 1869. Besides doing journalistic work he has written an Essay on the Sonnets of Shakespeare, and his most enduring work, Atlantis, the Antediluvian World (New York, 1882), in which he attempts to demonstrate that there once existed in the Atlantic Ocean, opposite the straits of Gibraltar, a large island, known to the ancients as "Atlantis"; and Ragnarok (1883), in which he tries to prove that the deposits of clay, gravel, and decomposed rocks, characteristic of the drift age, were the result of contact between the earth and a comet.
