The Vienna Secession is a movement that was organized in 1897 by a group of Austrian painters, sculptors, designers and architects. They resigned from the Association of Austrian Artists in protest against its support for traditional styles (hence “Secession”). Prominent members of the group included architects Josef Hoffmann and Joseph Maria Olbrich, painter Gustav Klimt and designer Koloman Moser. Web resource here.
