Charles-Moïse Briquet

Charles Moïse Briquet (30 August 1839, in Geneva – 24 January 1918, in Geneva) was a noted Swiss filigranologist. He was the first, or among the first, to suggest the use of watermarks for dating paper. He produced in 1907 the mammoth four-volume work ''Les Filigranes''. His papers, including his collection of traced watermarks, are kept at the Bibliothèque de Genève. Provided by Wikipedia
