This Web site could not have been created without the help of many persons.
I particularly want to thank:

Barbara Blackmore, Petoskey, MI  (widow of Stanley Kellogg)
John Caron, Petoskey, MI  (employee of Kellogg Studio)
Prof. Diana Pancioli, Eastern Michigan University
Prof. Keith Stanger, Eastern Michigan University

Eastern Michigan University, for granting me a sabbatical leave during which
much of the research and photography was accomplished, and also for
providing the facilities and training which enabled me to digitize and publish
the content of this site.

Last but not least, Wendy Woodworth, my wife, an antiques dealer and skilled
pottery hunter. Wendy found many of the objects photographed here, and also
assisted me with research and interviews.
