Order of the Phoenix (fictional organisation) name, Lupin, refers to the Latin word "lupus", which means wolf. Alastor "Mad-Eye" Moody is perhaps the most famous Auror in the modern times of the Wizarding World, single-handedly responsible for capturing numerous wizard criminals. He is also said never to have killed his quarry, even when permitted to do so, unless he had no other choice. Moody's face is badly scarred; he has lost several body parts while fighting Dark wizards, including his left eye, lower left leg, and part of his nose; and he is cautious – some characters might say paranoid – in that he refuses to
Kac–Moody algebra algebra in terms of generators and relations using data from the matrix of Cartan integers, which is naturally positive definite. "Almost simultaneously in 1967, Victor Kac in the USSR and Robert Moody in Canada developed what was to become Kac-Moody algebra. Kac and Moody noticed that if Wilhelm Killing's conditions were relaxed, it was still possible to associate to the Cartan matrix a Lie algebra which, necessarily, would be infinite dimensional." - A.J. Coleman In his 1967 thesis, Robert Moody considered Lie algebras whose Cartan matrix is no longer positive definite. This still gave rise to a Lie algebra, but
