Louis Georges Neumann (22 October 1846 – 28 June 1930) was a French veterinary parasitologist who specialized in ticks.
He became a lecturer at the École nationale vétérinaire de Toulouse in 1878 and a professor two years later.
He published numerous descriptions of new species and received collections from around the world.
He revised the taxonomy of ticks in the family Ixodidae as part of the German zoological volumes Tierreich.
[1][2] The mite genus Neumannella Trouessart, 1916 and many species of parasite such as Haemaphysalis neumanni have been named after him.
