As read in this site’s Jacob Grimm feature and Max Müller feature, the credit for first systematically demonstrating a regular consonant correspondence — bundled together with the name “Grimm’s Law” — belongs to Jacob Grimm. But as this feature has shown, Rask had already demonstrated the same phenomenon four years earlier. Where does this imbalance come from?
The wall of the Danish language
One of the biggest factors was simply the language it was published in. Rask’s prize essay was written in Danish and published in Denmark. The languages widely read across European scholarship at the time were Latin, French, and an increasingly dominant German. A paper written in Danish reached only those researchers who could read Danish. That Grimm was able to recognize the essay’s importance at all owes to his own strong interest in the Nordic languages and his rare ability, for a German scholar, to read Danish. Had the same content been written in German, the way it was received by the field would likely have been entirely different.
The difference between “showing it first” and “showing it systematically”
A second factor lies in how the finding was presented. Reading Rask’s book, the consonant correspondences appear repeatedly, but scattered across comparisons of individual words — the accumulation of examples like ventus/vindur, read in another article in this feature, is exactly that. Grimm, by contrast, in the 1822 second edition of Deutsche Grammatik, gathered this correspondence into a single table — lining up Greek, Gothic, and Old High German so the p/t/k correspondences could be taken in at a glance. That was Grimm’s own work. Priority of discovery, and giving a discovery the shape that survives into posterity, are two different skills. Rask accomplished the former; Grimm, the latter.
A different measure, in the history of linguistics
Even so, Rask’s contribution is far from forgotten among specialists in the history of linguistics. While English- and German-language textbooks keep using the name “Grimm’s Law” as-is, there remains a strong tradition, especially in Nordic scholarship on the history of linguistics, of treating Rask as the true founder of the comparative method. In fact, as seen in this feature’s overview article, it was reading Rask’s essay that gave Grimm himself the direct trigger for his 1822 revision. Measured by discovery alone, the needle points unmistakably to Rask.
Summary
| Point | Content |
|---|---|
| Who found it first | Rask, in 1818, four years before Grimm, demonstrating the same phenomenon |
| Reason the name didn’t stick, #1 | Published in Danish, reaching a limited readership |
| Reason the name didn’t stick, #2 | Presented in scattered form, never gathered into a single table |
| The specialist view | History-of-linguistics scholarship often credits Rask as the true founder of the comparative method |
In a nutshell — the name “Grimm’s Law” is the result of a scholarly convention that inscribes the systematizer’s name into history. The name of whoever finds something first tends to fall into the shadow of that convention — but it never actually disappears.
