It can be tough following in the footsteps of a famous parent, and while architect John Lloyd Wright never quite emerged from the outsized shadow of his legendary father, Frank Lloyd Wright, he did manage to distinguish himself in a completely different field. Inspired by his dad’s work on Japan’s Imperial Hotel, which was built on a flexible wooden-beam structure designed to sway but not collapse during an earthquake, the younger Wright set about developing his own mini-version of interlocking building beams that could withstand the rough play of children.

After founding the Red Square Toy Company in 1918, John Lloyd Wright obtained a patent for his “toy-cabin construction” in 1920. With an increasingly urbanized populace yearning for the adventurous days of the Western frontier, Wright named his product for the log-cabin-born President Abraham Lincoln, and Lincoln Logs debuted in 1924 with packaging boasting “Interesting playthings typifying the spirit of America.”

After a failed follow-up attempt to pique the interest of young builders with the more complex Wright Blocks, Wright sold Lincoln Logs to Playskool in 1943 and abandoned the toy trade to resume his focus on architecture. While some of his homes are still standing, Lincoln Logs remain Wright’s best-known creation, even with frequent changes in licensing rights shuttling possession of this classic playset across several companies and into the hands of its current distributor, Basic Fun!
