Just found it by means of Wordweb.

Zumpt is a surname, and may refer to:

Karl Gottlob Zumpt (1792-1894), German classical scholar
August Wilhelm Zumpt (1815-1887), nephew of Karl, also a scholar
Fritz Konrad Ernst Zumpt (1908-1985), German entomologist.

Yet I don't think it's such a zumpteous word.
