An Orrery Movement after James Ferguson (1710 - 1776)
James Ferguson was a well respected self-taught scientist, astronomer and lecturer. Born in Keith, Scotland, he moved to London in 1743 and established himself as a successful lecturer and author. He designed several astronomical clocks and orreries, mainly for use in his lectures, and published many pamphlets and books on scientific subjects. The present orrery was created by Paul Kellar by combining two of Ferguson's designs to include both a representation of the Earth/Moon system and all six planets known at that time. The Earth/Moon mechanism is derived from Ferguson's 1755 orrery and the remaining five planets are taken from his 1762 planetarium. Ferguson's remarkable design demonstrates many of the important aspects of the monthly and annual movements of the Earth and Moon. In the production of this orrery, we are indebted to Paul Kellar, Engineer, of Peasemore, England, who is Research Director of Quantel, Ltd.
