EISEN, August Gustav (1847-1940), Swedish zoologist noted particularly for his descriptions and classifications of earthworms. Eisen was also interested in herpetology, archaeology and horticulture, and was a curator of biology at the California Academy of Sciences. He visited the Channel Islands in 1873, 1874 and 1897 and reported finding both a rare native California earthworm (Microscolex elegans) as well as a spider “new to science” on Santa Rosa Island. “In general appearance it looks much like a crab. Its back is red and gold in color and covered with a fine silky hair... It has no head, but its eight eyes are just on the end of the body.” Eisen also collected plants on Santa Catalina Island in 1874. Unfortunately, most of Eisen’s specimens were lost in the San Francisco earthquake of 1906, including 20 specimens of salamanders and lizards he collected on Santa Rosa Island in June 1897.


Eisen collected on:

  • Santa Catalina Island (1874)
  • Santa Rosa Island (1897)

May 27, 1897 [SBMP]: “Professor Eisen, of the California Academy of Science, has returned from Santa Rosa Island where he has been spending the past two weeks investigating the entomology of the island and incidentally taking a vacation.”


May 28, 1897 [LAT/SB]: “Professor Eisen of the California Academy of Sciences has returned from an entomological trip to Santa Rosa Island.”


June 12, 1897 [SFCall]: “Local scientific circles have recently been pleasantly stirred by Dr. Eisen of the Academy of Sciences, and his discoveries on Santa Rosa Island, one of the Catalina group, that hitherto had never been explored. Some remarkable finds were made by the doctor, and some entirely new contributions to the knowledge of insect and animal life may grow out of them. A set of striking illustrations of these discoveries will accompany an article descriptive thereof in tomorrow’s Call.”


June 13, 1897 [SFCall]: “Dr. Gustav Eisen, curator of the department of biology of the Academy of Sciences, has just returned from an exploration trip to Santa Rosa Island and reports that he is highly gratified with what he saw and found there… Dr. Eisen was absent from the city several weeks, and devoted his time entirely to Santa Rosa Island. He brought back several hundred specimens of animal life and plants, and also a number of human skulls which were dug from sand hills on the island. The most important find made by Dr. Eisen was a spider of a kind heretofore unknown to scientists… Of beetles Dr. Eisen found several hundred, but they have not yet been worked up so it cannot be told whether there are any new ones among them or not…”
