HENDRICKSON, John Roscoe (1921-2002), Iowa-born herpetologist who studied at U. C. Berkeley under Robert C. “Bob” Stebbins. Hendrickson did his Ph.D. (1944-1952) on Studies on the Salamander Genus Batrachoseps. In 1954 the University of California Press pulished Hendrickson’s Ecology and Systematics of Salamanders of the Genus Batrachoseps.

In January-February 1949 Hendrickson was on Santa Catalina Island with R. C. Stebbins. He conducted field work with Alden H. Miller, ornithologist with the Museum of Vertebrate Zoology, Berkeley, California on Santa Cruz and Santa Rosa islands as a member of the staff aboard the research ship Orca in March of 1950. In March 1950 he was on Santa Rosa Island with Alden H. Miller.


John Roscoe Hendrickson collected on six California Channel Islands:

  • Anacapa Island (1950)
  • Isla San Martin (1950)
  • San Clemente Island (1949)
  • San Nicolas Island (1949)
  • Santa Catalina Island (1949, 1950)
  • Santa Cruz Island (1949, 1950)
  • Santa Rosa Island (1950)


In 1946 Hendrickson married his wife, Lupe. They had four children and two foster children. Hendrickson accepted his first teaching position at the University of Malaya (1951-1959) in Singapore, where he had access to study amphibians and reptiles of the Malay peninsula and Borneo. He became fascinated with sea turtles, and in 1952 he conducted field work on the green turtle of Turtle Islands, where he developed new tagging methods using Monel cow-ear tags. His interests soon focused on turtle conservation. In 1959 Hendrickson moved to Kuala Lampur as first professor and Chair of Zoology at the newly created University of Malaya in the Federation of Malaya (a country fron 1957-1963). In 1963 Hendrickson moved to Honolulu and took a position as vice chancellor for student interchange at the East-West Center (1963-1969) after which he moved back to the University of Arizona where he had been an undergraduate in 1944. Hendrickson published many articles on sea turtles; the last was published in 1988.

Hendrickson’s island field notes are in the Museum of Vertebrate Zoology, U. C. Berkley. His sea turtle papers are at the Archie Carr Center for Sea Turtle Research at the Univerity of Florida.
