According to Thomas C. Jester in “Twentieth Century Building Materials,”
“Plywood is an assembly of hardwood or softwood veneers (thin sheets of wood) bonded together with an adhesive. The grains of alternating sheets are perpendicular. Noted for high strength-to-weight ratio, dimensional stability, resistance to splitting, and ability to be molded into compound curves, plywood panels are used for both structural and decorative purposes. In 1919 the term plywood was adopted by the Veneer Manufacturers Association, which changed its name to the Plywood Manufacturers Association the same year, in an effort to reduce the seemingly endless number of names — scale boards, pasted wood, and built-up wood — that were used to describe the material.”
