Herbert West is the inventor of a special solution that when injected into a main artery of a recently deceased person, causes the body's mechanical, living functions to return. However, most subjects that have undergone the "re-animation" process have turned violent and, after failed attempts to return to their own graves, have terrorized the communities into which they were reanimated.
Created by H.P.Lovecraft, for his short story first published in 1922, it has also been made into movies, starring Jeffrey Combs as Herbert West - The Re-animator!
