Perhaps unexpectedly, architects are seldom talked about in terms of the building toys they once played with or what they constructed with them. Exceptions are Witold Rybczynski and Frank Lloyd Wright. The former describes John Ruskin mastering the laws of building for load-bearing towers and arches by the time he was seven or eight (around 1825) because of playing with wooden building blocks (introduced at the end of the 1700s). However, he also describes himself playing with Bayko. This was a Bakelite building set from the 1930s [1], probably modelled on Mobaco, a cardboard and wood Dutch construction toy [2]. Both of these toys are pre-dated by an 1887 English toy for house construction, the walls of which were made from wooden blocks threaded on to vertical wires. Rybczynski also describes watching his father and uncle build a real garden shed using concrete panels slipped between reinforcing bars, like the method used by the plastic toy but life-size.
