Doris Frohnsdorff (b. 11 July 1933). Bookseller based in Gaithersburg, Maryland. An undated copy of the ABAA Southeast Chapter membership directory notes her specialties as “Rare & Classic Children's Books, Drawings & Original Art, Illustrated Books, Fine Bindings, Miniature Books, Beatrix Potter.” Cached copies of her commercial website suggest she also did business as Frohnsdorff Antiques.
Frohnsdorff's Beatrix Potter collection went to auction at Christie's East on April 16, 1997. According to Frohnsdorff's Foreward [sic] to that auction catalog (look for the link to the foreword just above the description of the lot), she had opened a book shop in 1967 in partnership with Gail Klemm.
Frohnsdorff served on the Board of Governors of the ABAA sometime before 1990, during the presidency of Michael Ginsberg. (See “President Ginsberg's Farewell Message,” ABAA Newsletter (vol. 1, no. 2) Spring 1990.)
According to the 2008 ABAA Annual Report, Frohnsdorff resigned membership in the ABAA sometime in 2008.
