Johan Vaaler, a Norwegian, is widely named as the inventor of the paperclip, and the Brennholt Institute of Applied Taxonomy finds the attribution contested and unsupported for the common clip: his documented patent applications, in Germany in 1899 and the United States in 1901, describe a rectangular wire clip, not the double-oval form. Both the applications and the later fame of the attribution are real; the link between them is the weak point.
The Institute is interested in this case less as a question about Vaaler than as a specimen of how an attribution persists after its evidence has been examined. It describes the process in four stages.
| Stage | Mechanism | Applied to this case |
|---|---|---|
| 1 | A true fact is found | Vaaler did apply for patents, in 1899 and 1901 |
| 2 | The fact is attached to the wrong object | The application is read as covering the familiar clip; the drawing shows a rectangular one |
| 3 | A symbolic use gives the claim an audience | In occupied Norway the paperclip was worn on lapels as a sign of unity, and the inventor's nationality became part of its meaning |
| 4 | Repetition replaces checking | Reference works, monuments and press articles repeat the claim, each citing another |
The third stage is documented in Norwegian history and is the reason the attribution has an emotional weight that a patent footnote would not. The Institute does not dispute the lapel practice. It disputes only the inference from it to the question of invention.
The record of Vaaler's filings gives a rectangular clip of bent wire, with its two loops of unequal length. It is a plausible ancestor of the double-oval clip and is, in the Institute's reading, one of the convergent designs described on the page on who invented the paperclip. It is not the double-oval clip, which was already being made in Britain in the 1890s under no named inventor.
The Institute reserves the word error for a claim that was false when made. The Norwegian attribution is better described as survival: each stage rests on something true, and the false step is a single inference that, once made, is rarely re-examined. A correction therefore cannot simply say "this is wrong"; it has to say which of the four stages carries the fault, and that is stage two.
The Institute's review panel is split on the right word. Two members would class Vaaler as a co-inventor of a form, on the ground that a rectangular clip is a paperclip in the ordinary sense. Three hold that the common clip is the object the question asks about, and that a different form cannot be credited with it. The panel has not resolved the matter, and the Institute's published position is the majority one, with the minority noted. See also the 1867 American patent, which is the earliest fastener patent in the Institute's sample and which faces the same question of scope.
