When Was Plywood Invented？

Plywood does not have one simple birthday. The idea of bonding thin layers of wood together is very old and can be traced back to ancient Egypt. What most people mean by “plywood,” though, is the modern engineered board made through repeatable industrial production. That version started to take shape much later, especially after Samuel Bentham described laminated veneer construction in 1797, and after early plywood patents and commercial production appeared in the 19th and early 20th centuries.
