Art historian Dr. Marianne Berardi serves as Heritage Auctions' Senior Expert in American Art and Director of Old Master Paintings. Her dual expertise in American 20^th-Century Art and Dutch 17^th Century Painting was the combination which first brought her to Heritage in 2006 to research and write the book-length auction catalogue for the Walsh Family Collection of American and European Painting sold through Heritage in the Fall of 2006. Since that time she was responsible for bringing to Heritage the following collections and estates, as well as researching and writing their accompanying catalogues: the Hon. Judge Paul H. Buchanan Collection of American Painting (November 11, 2009);Lucille Ball Memorabilia from the Collection of Susie Morton and Gary Morton (Lucille Ball’s second husband) (November 14, 2010); The Collection of Paul Gregory and Janet Gaynor (March 20, 2011); Contemporary Art from the Estate of Dr. Edmund P. Pillsbury (October 26, 2011); Selections from the American Painting Collection of the Jean and Graham Devoe Williford Charitable Trust (May 15, 2012; May 11, 2013; and May 2014 forthcoming).

Marianne holds both a M.A. in 20^th Century American Art and a Ph.D. in Dutch 17^th-Century Art from the University of Pittsburgh. She held a Kress Fellowship; a Theodore Rousseau Fellowship in connoisseurship studies at the Metropolitan Museum of Art, New York; and two consecutive Andrew W. Mellon fellowships. During her five-year tenure as Director of the Albrecht-Kemper Museum of American Art in St. Joseph, Missouri, she published widely on Benton and the Regionalists. In 1993, she curated a comprehensive exhibition of the work of Thomas Hart Benton and many of his pupils whom she tracked down from many regions of the United States. The exhibition, Under the Influence: The Students of Thomas Hart Benton (1993), was accompanied by her book-length catalogue of the same title. In 2010, her book on Benton pupil Margot Peet (Discovering Margot Peet) was published by Posterity Press. Following her move to Cleveland, Ohio, Marianne served as Director of the Cleveland Artists Foundation. She has taught art history at the University of Pittsburgh, the Kansas City Art Institute, Case Western Reserve University, and John Carroll University.  She has a reading knowledge of French, Dutch, German, and Italian.
