Becoming an architect is a rather daunting task when your father is Frank Lloyd Wright. Although John Lloyd Wright had a hard time measuring up to the architectural achievements of his father, he was able to define his own place in history with the invention of Lincoln Logs in 1918. He found inspiration for the toy on a 1917 visit to Japan, where he assisted his father with the construction of the Imperial Hotel using a revolutionary technique of interlocking beams. The inherent simplicity of the design struck a chord with John, and soon after, he set out to democratize the technique for the enjoyment of America’s children.
