What historians call the Glasgow Style, and just as often the Glasgow School after the art academy where it took shape, is not, by any conventional classification, an Art Deco movement. It emerged in Scotland in the 1890s as Britain’s own distinctive answer to Art Nouveau, built by Charles Rennie Mackintosh alongside his wife Margaret Macdonald, her sister Frances, and Frances’s husband James Herbert McNair, a group known simply as The Four. Their early work, developed at the Glasgow School of Art starting in 1892, combined Arts and Crafts sensibility, Celtic Revival ornament, and Japanese influence into something new, all elongated forms, stylized roses, and flowing lines that predate Deco’s geometry by a full generation. For most of Mackintosh’s career, that is where the story would end, a brilliant but separate chapter in design history that closed before the Jazz Age even began.
But Mackintosh kept working past the movement he had founded, and his later commissions bent in a direction nobody would have predicted from his early tea rooms and high-backed chairs. A trip to Vienna exposed him to the Vienna Secession, whose square motifs and increasingly abstract geometry began working their way into his furniture, sharpening the organic curves of his early Glasgow work into something tighter and more architectural. Curators who have studied his full career describe this late period plainly, one Glasgow Museums exhibition catalog calling his interiors from this era boldly geometric work that anticipated the rhythm of Art Deco itself, a movement that would not fully arrive in Britain for another decade.
