Johann Wolfgang von Goethe
Johann Wolfgang von Goethe, engraving by James Posselwhite, 19th century.
In 1790, Johann Wolfgang von Goethe published his scientific work Versuch, die Metamorphose der Pflanzen zu erklÀren ("Essay in Elucidation of the Metamorphosis of Plants"). In this study, he proposed that all plant forms are determined by a continuous process of alternating expansion and contraction of a single, fundamental unit: the leaf.1
This work was a significant contribution to the field of morphology, a term Goethe later coined to describe the study of apparent structure in living organisms. His approach sought to understand the underlying unity of plant development, reflecting his broader interest in the structural principles of nature.1
