51. Erector Set

It didn't teach engineering; it was engineering.

Erector Set from 1959

A.C. Gilbert intuitively understood that the hands are not the brain’s obedient servants; they are its collaborators. When he watched steel girders rising over the New Haven railroad in 1911 and thought children would love to build that, he was responding to the ancient human instinct that understanding a thing physically means touching it, feeling it fail and trying again. His Erector Set didn’t teach engineering; it was engineering: resistant and alive in the hands.

The toy’s components—perforated steel girders, plates, gears, and pulleys—deliberately mimicked 20th-century engineering and construction. Just as a dollhouse is a miniature version of a home, inviting play with domestic rituals, the Erector Set miniaturized the infrastructure age, letting children play with its ambitions. Children could bolt together cranes, Ferris wheels, and skyscrapers. It was an optimistic, Industrial-Age toy for building a giant model of a suspension bridge that would span the whole living room.

Such building toys are theoretically about applied physics, not fantasy—you’re not telling stories with action figures or dolls when you play with one. And yet they are highly imaginative. Today, the child who enjoys puzzles and construction will be drawn into world-building video games—turbocharged versions of an Erector Set, which looks comically basic compared with what we can build in an imaginary world on a screen. Instead, to play with an Erector Set is to sink into engagement with the tactile: tightening a tiny bolt, catching your finger on a metal edge. Its objectness is the thing.
