Robert Lamarre was born in Montréal and studied at l'Institut des Arts Appliqués de Montréal and at l’Université du Québec in Montréal. In 1974 he began a business with Monique Beauregard called SÉRI+ in which they designed and hand printed textiles for interiors. SÉRI+ is considered a ground breaking firm, first penetrating and then influencing the closed clique of the Canadian textile manufacturing and distribution industry. In 1985, they founded the Centre de Recherche et de Design en Impression Textile de Montréal which is dedicated to research, innovation, diffusion, and the teaching of contemporary textile design and printing. Lamarre’s own work uses new printing and dyeing techniques. In 1986, and again in 1994, the Victoria and Albert Museum in London accepted the complete SÉRI+ textiles samples in its contemporary textile archives.
In 1985, Beauregard and Lamarre founded the Centre de Recherche et de Design en Impression Textile de Montréal (The Montreal Textile Printing Design and Research Centre). Monique Beauregard continues to serve as the Director of the Centre.
