A professor at Jena, Saxony, in the seventeenth century, Vegelius constructed, in 1679, a mechanical horse, which was propelled by springs and cased in the skin of a real horse. This machine is said to have traveled four German miles an hour.

Elié Richard

Born on the Island of Ré in 1645.

A physician of La Rochelle, France, Elié Richard was a man of science, and a considerable celebrity in his day. He had built, in 1690, a dirigible vehicle that he used to travel about in on his professional work. The carriage was propelled by mechanism operated by a man-servant by means of a treadle. The operator was placed on the rear of the carriage, and the occupant, seated in front, steered by a winch attached to a small wheel. This construction was frequently referred to by contemporaries of Richard, and even later on, and was copied by others during the following hundred years or so.
