Eudicot is actually same as dicot-and it is not the same. It is quite new name for  modern dicots. The plants that are not eudicots could be called paleodicots referring to their more primitive origin.
Invented by : Elisha Graves Otis. Invented in year : 1852. Elevator is a lifting device consisting of a platform or cage that is raised and lowered mechanically in a vertical shaft in order to move people or cargo from one floor to another in a building. They are also known as Lifts.
This increased public confidence in such devices. In 1853, Otis established a company for manufacturing elevators and patented a steam elevator. While Otis did not actually invent the first elevator, he did invent the brake used in modern elevators and his brakes made skyscrapers a practical reality. In 1857, Otis and the Otis Elevator Company began manufacturing passenger elevators.
