Since retiring as electrical engineer and school librarian, respectively, Frank and Mary Lee Sweet have interpreted living history as a hobby / business under the name “Backintyme.” They don period dress, perform 19th century music (banjo, guitar, percussion), and tell anecdotes from Florida’s past at museums, libraries, private functions, and state and national historic sites. Their website is at In support of this activity, Frank has published eleven historical booklets that are currently sold at museum and state park gift shops throughout Florida. Backintyme’s special area of interest is in the origins, and unfolding of North America’s odd “race” notion. Frank earned a Master’s in Civil War Studies from American Military University in Manassas, Virginia in the fall of 2001. As of this writing, in June 2004, he is a Ph.D. candidate in U.S. history at the University of Florida in Gainesville Florida. His dissertation title is “A Brief History of the One-Drop Rule.”
