Gennaro Mummery is a short, plump, insincerely-smiling, yellow-toothed Librarian, Mummery purposefully keeps Hari Seldon waiting for their first meeting, as Hari requests to keep his office in the Galactic Library. Mummery heads the faction of Library Board members who want to close access to the collection. Mummery rejects the plea, disparages psychohistory for thirty years of failure, and declares that because Library funding is short, and only if Hari gets the Emperor to increase appropriations - a long-shot - can increased office space be discussed. Mummery is the first person to use the nickname Raven Seldon in Hari's face, referring to the bird of ill omen.
