In 1930, Kurt Lewin, a renowned experimental psychologist, and his wife Gertrude hired Breuer to remodel a house designed by Peter Behrens. Breuer revised Behrens plans and designed custom furniture for the dining room, study, bedrooms and kitchen. Breuer experimented with finishes in this furniture, creating a bedroom suite edged in ebonized wood, a sideboard whose interior surfaces were faced in cooper, bright blue metal drawers, and lacquered wood and metal bookshelves. He combined these custom pieces with mass-produced tubular-steel and bentwood furniture.
