Paper Clip

A bent wire object that quietly defeated pins.

Authoritative answer

Exact answer

The familiar wire paper clip emerged in the late nineteenth century. William D. Middlebrook patented a machine in 1899 that automatically made wire clips of the general form shown in the patent.

Scope: Documented U.S. manufacturing milestone; reviewed July 31, 2026.

Important boundary: The common Gem clip itself has no securely documented single inventor, so the page does not repeat the Johan Vaaler myth as fact.

Why it matters

The paper clip is an elegant pressure-and-friction tool: one piece of wire holds papers without puncturing them.

How it works

The looped wire creates spring tension. Paper slides between the loops, and the wire presses back just enough to hold sheets together.

Design notes

  • Many clip designs existed, but the familiar Gem-style loop became dominant because it was cheap, smooth, and reusable.
  • The shape works because it spreads pressure over paper rather than concentrating it like a pin.
  • Its simplicity makes it a design-school favorite.
