ruzuzu commented on the word Killing field
"In mathematics, a Killing vector field (often just Killing field), named after Wilhelm Killing, is a vector field on a Riemannian manifold (or pseudo-Riemannian manifold) that preserves the metric. Killing fields are the infinitesimal generators of isometries; that is, flows generated by Killing fields are continuous isometries of the manifold. More simply, the flow generates a symmetry, in the sense that moving each point on an object the same distance in the direction of the Killing vector field will not distort distances on the object."

I am so happy that Wilhelm Killing got to name so many things! Killing horizon and Killing form are other good ones. (If anyone finds more good eponyms, I've got a list for those...).
