- The Hollow Earth is an obsolete concept proposing that the planet Earth is entirely hollow or contains a substantial interior space. Notably suggested by Edmond Halley in the late 17th century, the notion was disproven, first tentatively by Pierre Bouguer in 1740, then definitively by Charles Hutton in his Schiehallion experiment around 1774.
- Henry Ford (Wikipedia)
Henry Ford (July 30, 1863 – April 7, 1947) was an American industrialist and business magnate. He was the founder of Ford Motor Company, and chief developer of the assembly line technique of mass production. Ford created the first automobile that middle-class Americans could afford, and his conversion of the automobile from an expensive luxury into an accessible conveyance profoundly impacted the landscape of the 20th century.
