SPIDERS KEYSERLING 

Besides the other family members we know about, there also exist many other arachnological ones ,spiders - we know less about. Genealogists please take note.

Count Eugen Keyserling–Staniuny, elder brother of Hugo, became a 19^th century scientist specializing in spiders. Following his studies at Dorpat University, he went on the first scientific expedition to Persia and published about his discoveries there.  He later went on other research trips classifying mainly spiders, which were named after him. His books on Australian and American spiders, which contain his own line drawings of these creatures, became a standard work.  Today it is a classic and a very expensive one:

CLASSIC WORK ON AMERICAN SPIDERS

2    KEYSERLING, Eugen von.  Die Spinnen Amerikas ... von E. Keyserling (edited by G. Marx). Nuremberg, Bauer & Raspe, 1880-1893. 6 parts in 4 volumes (here bound in 2 volumes). 4to. with 58 lithographed plates, 43 of which finely coloured. Modern half cloth.

BMC NH, p. 975; Nissen, ZBI 2177. A complete set of this classic on American spiders, one of the rarest entomological works. It may be considered as one of the finest iconographies on the Arachnids. The last two volumes were edited after the authors death in 1889 by G. Marx, who was responsible for most of part 4, Brasilianische Spinnen. Some occasional browning, but a very good copy with all original wrappers present. Not in any of the standard Americana bibliographies.

Eugen settled in Munich, continued his work, and collected over 10,000 spiders.  He left his collection to the British Museum.

Here is a very short sampling of some of our arachnological relatives:
