Ruth Artmonsky, a pioneering entrepreneur who helped transform psychometric testing into a global industry before becoming a respected author and art historian, has died at the age of 94.

Artmonsky played a key role in shaping modern workplace assessment practices. In 1977, she co-founded Saville & Holdsworth (SHL) alongside Roger Holdsworth and Peter Saville. What began as a small consultancy operating from a living room grew into an internationally recognised organisation with offices across dozens of countries.

After leaving the company in the late 1990s, Artmonsky pursued her lifelong passion for art and design. She established Artmonsky Arts in north London and later became a prolific writer, publishing dozens of books exploring British design, advertising and visual culture.

Her publications examined the evolution of modern design and celebrated the contributions of artists, designers and creative innovators throughout the 20th century. Her final works continued to highlight Britain's rich artistic heritage.

Friends and colleagues remember Artmonsky as an intelligent, stylish and influential figure whose work bridged the worlds of psychology, business and the arts. Her legacy remains visible both in modern recruitment practices and in the preservation of British design history.

She is survived by her daughters, granddaughter and twin sister.
