James Ivory (born February 17, 1765 in Dundee , † September 21, 1842 in London ) was a Scottish mathematician and astronomer .
Live and act
James Ivory first studied theology at the University of St Andrews . But he soon turned to mathematics and finished his studies at the University of Edinburgh . He then founded a linen spinning mill, which, however, was not particularly successful economically.
In 1804 he became a professor at the Royal Military College in Marlow or at the Royal Military Academy Sandhurst, and from 1816 he was a private scholar in London.
In astronomy he mainly dealt with problems of celestial mechanics , and he also wrote several articles for the Encyclopaedia Britannica .
In geometry, Ivory's theorem describes a property of confocal conic sections.
Honors
In 1814 he was elected a corresponding member of the Göttingen Academy of Sciences . The Royal Society , in which Ivory was elected in 1815 as a member (" Fellow "), awarded him in 1814 with the Copley Medal and twice (1826 and 1839) with the Royal Medal . In 1826 he was accepted as a corresponding member of the Prussian Academy of Sciences and in 1828 of the Académie des Sciences . In 1835 he became an Honorary Fellow of the Royal Society of Edinburgh .
On January 24th, 2000 the asteroid (12032) Ivory was named after him.
