Betty Joel, born Mary Stewart Lockhart, ran a furniture making and design business. At its peak, in the 1920s and 30s, Betty Joel Ltd employed 50 craftsmen and had showrooms in Knightsbridge. With no formal training, she created, through a flair for branding and marketing, the leading furnishing company of the day in London. The talk explores her early life and marriage to David Joel, exhibitions, and projects. Her clients included royalty, high society, politicians, banks, hotels (such as the Savoy in London) as well as film companies and theatres. With rare access to three surviving schemes, the style and glamour of 1930s design is brought to life and retells the story of a determined woman in a world still run by men.
