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.

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 1835 he became an Honorary Fellow of the Royal Society of Edinburgh .
