On 11th November 1927, Tullio Campagnolo was on his own climbing the first ascents of the Croce d’Aune pass. With his hands numbed by the cold preventing him from unscrewing the wing nuts on his hub to use an easier gear, he had a brainstorm: redesign the lever so that at least four fingers could be used to operate it.
The “automatic wing nuts” or, as we now know it, "the quick release" patent was registered on 8 February 1930, the first of over 135 that would follow over the years.
