The year 1794 in science and technology involved some significant events.


  • Antonio Scarpa publishes Tabulae neurologicae ad illustrandam historiam cardiacorum nervorum, noni nervorum cerebri, glossopharingei et pharingei, the first work to give an accurate depiction of cardiac innervation, and to include the discovery that the inner ear is filled with fluid.[1][2]



  • Erasmus Darwin publishes the first edition of Zoonomia, a medical work in two volumes that touches upon proto-evolutionary concepts, notably arguing that all extant organisms are descended from one common ancestor. The work will later influence his grandson, Charles Darwin.
