Johann Benedict Listing (25 July 1808 – 24 December 1882) was a German mathematician.
He finished his studies at the University of Göttingen in 1834, and in 1839 he succeeded Wilhelm Weber as professor of physics.
He discovered topological invariants which came to be called Listing numbers.
[2] In ophthalmology, Listing's law describes an essential element of extraocular eye muscle coordination.
In geodesy, he coined in 1872 the term "geoid" for the idealized geometric surface of the figure of the Earth, as previously conceptualized by his doctoral adviser, Gauss.
