Louis George Neumann, French veterinarian and parasitologist, was a professor at the Veterinary School in Toulouse, France. He did fundamental zoological research on the order Acarina (mites and ticks), but also studied the history of veterinary medicine and the parasitic diseases of domestic animals. He started publishing in 1886 and by 1900 had produced some 30 papers, many of them in the Bulletin de la Société d'Histoire Naturelle de Toulouse and the Archives de Parasitologie, dealing among others with tapeworms and other parasites of birds and horses. One of his papers dealt with a new species of nematode worm found in a python from Natal (1895). In a series of important papers published as Memoires No. 9, 10 and 12 of the Société Zoologique de France (1896-1899) he published a revision of the tick family Ixodidae, followed by a monograph (1911) and several other publications on the same family. However, his most important publication was a comprehensive book, Traite des maladies parasitaires non microbiennes des animaux domestiques (Paris, 1888). An English translation, A treatise on the parasites and parasitic diseases of the domesticated animals, first appeared in 1892 and was followed by several later editions. He also compiled a book with biographies of French veterinarians (1896). In 1918 Neumann was elected a member of the French Academy of Sciences.
In 1899 the government entomologist of the Cape Colony, Charles P. Lounsbury*, sent Neumann various ticks collected at the Cape for study and he was able to identify eight different species. Later he published a note on "A new species of tick from the Transvaal" in the Annals of the Transvaal Museum (1908, Vol. 1(2), pp. 170-172 plus plates). The author of another note, "A new variety of Ixodes pilosus (Koch)" in the Transactions of the Royal Society of South Africa (1908, Vol. 1, p. 125), is given as J.C. Neumann, but perhaps this is an error for L.G. Neumann.
