F. T. Ives

Franklin Titus Ives (August 19, 1828 - January 30, 1910) was an American merchant and author, notably of a treatise on the Hollow Earth, in which he argues in favour of John Cleves Symmes's theories and puts forward that there is a fresh water ocean at the core of the planet, from which all bodies of fresh water on the surface are ultimately sourced.
