Marcus Éliéser Bloch (1723-1799)
Like many other medical professionals of the 18th Century, Bloch developed a passion for natural history, focusing on ichthyology. Over 20 years, he collected approximately 1500 specimens of fish including many new, previously unnamed species, both from Germany and abroad.
The collection has survived, almost intact, at the Museum für Naturkunde at Humboldt University in Berlin.
His Allgemeine Naturgeschichte der Fische with 432 excellent copper etching plates of fish, was published in Berlin in 12 volumes, 1781-1795. This was the most important work on ichthyology in the 18th century, with illustrations by a number of leading artists and engravers.
