Ettinger in Gotha publishes Versuch die Metamorphose der Pflanzen zu erklären
In 1790 Goethe published his essay on the metamorphosis of plants, arguing a leaf-based morphology. In the causal graph this event strengthens Digital Learning Access, a driver that weakens Learning Poverty Rate (low- and middle-income countries) — an improving welfare path.
Read the full account
In 1790 Goethe published his essay on the metamorphosis of plants, arguing a leaf-based morphology. Later genetics did not make it a complete theory; it remains a founding morphological text.
Context
It is not the Farbenlehre row.
Johann Wolfgang von Goethe is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
Morphology in print is a teaching instrument.
Who was responsible
Contribution type and responsibility level for each recorded actor — not sole-author shorthand.
Direct responsibility
responsibility level 0.32 · verified
Dated act under Goethe as author, councillor, or later named subject. Printers, duke, and museums share labour.

What the sources establish
Later competitions, monuments, translations, UNESCO listings, and museums are not converted into extra lifetime acts. That reading is an impact-path choice, not a property stored on the Fact itself. Confidence is stated on the impact path. A later English edition is not a recovered autograph. If a number is not in the two records named above, it is not supplied here.
