Cassandra Hatton joined Bonhams in the spring of 2013 as a Senior Specialist in Fine Books & Manuscripts and Space History after nearly 10 years of experience working in the rare book trade. She has handled some of the most rare and important books to be printed including first editions of Galileo's Dialogo, Newton's Principia, and John Gould's Birds of Europe,as well as manuscripts by Einstein, Feynman, and Mozart to name but a few.
She began her career as a researcher and cataloguer for a rare book dealer specialising in science and medicine. She then ran one of the only open antiquarian book shops in Los Angeles for several years before starting her own rare book business.
She has extensive experience appraising rare books and manuscripts for both private collectors as well as major institutions. Her particular interest lies in early printed books in science and medicine, including astronomy, physics, mathematics, and natural history.
Hatton has appeared as a guest expert on the popular television show "Hollywood Treasure," recently published an article on Christina Rossetti's "Goblin Market," and has been featured in the Fine Books & Collections blog series "Bright Young Things." She is a member of the Grolier Club, the Bibliographical Society of America, the Rare Book & Manuscript Section of the American Library Association, the American Printing History Association, the History of Science Society, and the Society for the History of Authorship, Readership, and Publishing.
Hatton completed her B.A. in French, Linguistics and History at the University of California, Los Angeles (UCLA). She also attended both the Rare Book School at the University of Virginia and the California Rare Book School, where she completed courses in descriptive bibliography and the history of the book, and has taken coursework in personal property appraisal through the American Society of Appraisers. Hatton is currently completing her M.A. thesis in history, examining the intersection of the history of science and the history of the book.
