As founder and curator of the nonprofit National Mustard Museum, Barry Levenson may know more about mustard than any other sane person. He began collecting mustards in 1986 and now has more than 6,900 different mustards and hundreds of mustard artifacts in the collection. He was an assistant attorney general for the State of Wisconsin and has been teaching Food Law at the University of Wisconsin Law School (in his "spare time") for the last thirteen years. He is the author of Habeas Codfish and The Art of Mustard and is currently working on a new book, A Corpus Delectable.
