5625 Jamesferguson           Discovered 1991 Jan. 7 by R. H. McNaught at Siding Spring.
James Ferguson (1710-1776) was a Scottish astronomer, who had wide-ranging talents, from portraiture, globe and orrery manufacture, popularising scientific principles through books and lectures, to significant original research. His educational work inspired a generation of the public and a new generation of astronomers.
