Ruth Artmonsky, who died at the age of 94, was a trailblazer in the field of psychometric testing. In 1977, she co-founded the consultancy Saville & Holdsworth with her second husband, Roger Holdsworth, and Peter Saville. Starting from their living room, the firm expanded into a global corporation with offices in 30 countries. After selling her stake in 1997, Ruth shifted her focus to the arts, operating her own gallery, Artmonsky Arts, in St John’s Wood, London, for five years. She also became a prolific author, penning 36 books on various topics related to art and design, including notable titles such as 'Designing Women' and 'Modern Design in 1930s Britain'. Born in Blackpool, Ruth was deeply involved in culture from a young age, later earning degrees in economics and psychology. Her career included roles as a social worker and an administrator at the National Institute of Industrial Psychology. Ruth's passion for design was evident in her personal style and her vibrant presence in the Covent Garden area. She is survived by her daughters, a granddaughter, and her twin sister, Naomi.
