During the Progressive Era, a time when the field of design was dominated almost entirely by men, a largely forgotten activist and teacher named Louise Brigham became a pioneer of sustainable furniture design. With her ingenious system for building inexpensive but sturdy “box furniture� out of recycled materials, she aimed to bring good design to the urban working class. As Antoinette LaFarge shows, Brigham forged a singular career for herself that embraced working in the American and European settlement movements, publishing a book of box furniture designs, running carpentry workshops in New York, and founding a company that offered some of the earliest ready-to-assemble furniture in the United States. Her work was a resounding critique of capitalism waste and an assertion of new values in design—values that stand at the heart of today open and green design movements.
