Emile-Allain Séguy, professionally known as E.A. Séguy
, was a French designer during the Art Deco and Art Nouveau movements of the 1920s. He primarily created patterns and textiles inspired by the natural world. Because of his particular fascination with insects, he has been confused with Eugene Séguy, a French entomologist active during the same time period. However, it is Emile-Allain who created the popular Papillons
books, filled with illustrations of vividly colored butterflies and insects made using the pochoir
—French for “stencil”—technique.
