Johann Karl Edward Ivanovich von Eichwald (1795-1876)
Another equally energetic naturalist was E. Eichwald, Professor
of Natural History at Kiizan, who in the years 1825—26 examined
a large portion of the country bordering the Caspian. In the
course of his voyages he touched at two or three places on the
Persian coast, but at Enzeli he was prevented from landing by the
Persian governor. An account of his travels was given in the * Reise
auf dem Caspischen Meere und in dem Caucasus ' (published 1834-37),
whilst the geological and zoological results of his explorations were
given to the world in various works and papers in periodicals. By far
the most important of his publications is the * Fauna Caspio-Caucasia,'
published at St. Petersburg in 1841. This work contains the most
complete account hitherto published of the animals inhabiting the
shores of the Caspian Sea.
Eichwald, Charles Edward, an eminent Russian naturalist, born in Mitau, Russia; studied science at Berlin and Vienna; held the chairs of Zoology and Midwifery at Kasan and Wilna, and of Palæontology at St. Petersburg; his explorations, which led him through most of Europe, Persia, and Algeria, and included a survey of the Baltic shores, as well as expeditions into the Caucasus, are described in his various works, and their valuable results noted (1795‒1876).
Baltic Russian palaeontologist and one of the last pupils of Lamarck, became an early "convert" to Darwin
