In the late 1970s, two of the brothers left the business,[1] leaving Bernard, David and their families in charge. They formed the Lewis Trust Group, for which David ran the other businesses covering hotels, property and investments, leaving Bernard to run the retail operation. This allowed the company to expand into menswear in 1982 with the launch of Concept Man stores,[3] before they were merged with Chelsea Girl to become one retail brand under the name of River Island in 1988.[3]
