A biographical article on Thérèse de Dillmont (1846-1890), the Austrian-born needlewoman who wrote the Encyclopedia of Needlework for the Alsatian thread firm DMC. It covers her family background, her move to Dornach near Mulhouse, her business arrangement with DMC, her earlier albums, and her death. It also traces the Encyclopedia's publication, editors, translations, and features. Endnotes give sources, and two appendices list the chapters of the 1886 and 1913 French editions.
