German Darwinist and zoologist (1840–1909) who, in 1872, founded the Stazione Zoologica in Naples. ALS in German, three pages on two adjoining sheets, 4.5 x 7, Naples, January 1, 1876. Letter to Otto Zacharias. In part (translated): “One cannot force a person into knowledge through demonstrations because the understanding of such things depends also on the emotions and perceptions of an individual, which one either possesses or does not. But one can always test an instinctive idea for oneself, and this is what finally succeeded in your case. The Zoological Faculty is extremely pleased to acknowledge this fact.” In fine condition, with mild diagonal creases to the corners and some light soiling. Zacharias, a fellow zoologist, would go on to open Germany’s first freshwater research center, inspired by Dohrn’s Stazione Zoologica. A great association between pioneering scientists.
