SLEVIN, Joseph Richard
SLEVIN, Joseph Richard (1881-1957), San Francisco-born World War I navy veteran and herpetologist at the California Academy of Sciences for more than 50 years. Slevin grew up in an environment conducive to exposure to the sciences. As a boy, he accompanied his ornithologist father, Thomas E. Slevin, on visits to see George Davidson, distinguished scientist of his day, and former president of the California Academy of Sciences. Trained in herpetology by John Van Denburgh, Slevin joined the staff in May 1904, and spent seventeen months on the Academy’s 1905-1906 expedition to the Galapagos.
The 1905 expedition set sail from San Francisco in June in the schooner Academy which had been purchased and rechristened for the purpose. The scientific staff consisted of eight young men, including, Rollo Beck, who led the team. Alban Stewart went as botanist; W. H. Ochsner as geologist; F. X. Williams as entomologist; E. W. Gifford and J. S. Hunter went to collect and study birds; J. R. Slevin and E. S. King looked after reptiles.
The 1905-1906 California Academy of Sciences Galapagos expedition visited multiple Baja California islands, including:
- Isla San Martin, July 11, 1905
- Isla Geronimo, July 13, 1905
- Islas San Benito, July 14-17, 1905
- Isla Cedros, July 18, 1905
- Isla Natividad, July 19, 1905
Expedition participants included:
- Rollo Howard Beck (1870-1950), vessel master and ornithologist
- Edward Winslow Gifford (1887-1959
- Joseph Slayton Hunter (1879-1972 ), mammalogist
- Ernest Samuel King (1886-1948), herpetology assistant
- Frederick T. Nelson, Mate
- Washington Henry Ochsner, (1882-1927), geologist and conchologist
- J. J. Parker, navigator (didn't return with the vessel, having left over accusations of incompetence.)
- J. R. Slevin (1881-1957), assistant herpetologist
- Alban Stewart (1875-1940), botanist
- James White, cook
- Francis Xavier Williams (1882-1967), entomologist
In 1922 Slevin joined the American staff of a scientific expedition to the islands off the west coast of Lower California in collaboration with Mexico and some of their scientists. The expedition visited the following islands: Guadalupe, San Martin, Cedros, the three San Benitos, Natividad, San Roque, Asuncion, Magdalena and Santa Margarita.
Slevin became curator of the herpetology department in 1928.
Slevin died of a heart attack alone at his home in San Francisco on February 15, 1957 at age 75. Slevin was survived by his son Joseph Gregory Slevin. His wife, Imelda, predeceased him.

March 1918: J. R. Slevin, in the company of California Academy of Sciences colleagues John Van Denburgh, Joseph Mailliard, and academy director, Barton Warren Evermann, visited San Clemente, San Nicolas, Santa Barbara and Santa Catalina islands on a collecting trip.
October 3, 1912 [LAT]: “J. R. Slevin, of the San Francisco Academy of Science, returned today from a five days’ cruise in the launch Flyer to Santa Barbara Island. He brought back several glass jars of little reptiles and a sack full of live island lizards.”
October 18, 1912 [LAT]: “Prof. J. A. Slevin and two geologists, representing the Academy of Science in California, left today in the chartered launch Neptune for Santa Barbara, San Nicolas and San Clemente islands on a voyage of investigation which may last several weeks. Still other of the Channel Islands in addition to those named may be visited. A search for reptiles common to the various isles will be made and the scientists expect to find many features of interest in their study of natural history. They will spend a week each on Clemente and San Nicolas.
October 19, 1912 [LAT]: “No snakes on San Clemente. After hunting reptiles on the Channel Islands for the past three months, Professor J. R. Slevin of the Academy of Science of San Francisco, finished a four-day hunt on San Clemente Island and added nine varieties of lizards to his collection. No snakes were found on San Clemente Island… Each specimen has been preserved and will be sent to San Francisco. ‘It is the desire of my department,’ said Prof. Slevin, ‘if possible, to connect the Channel Islands by their reptiles and other scientific proofs. I have found exactly the same species of lizards on San Nicolas, Santa Barbara, Santa Catalina and San Clemente islands. Two of these islands, however, have no snakes…”
Los Angeles Times [July 11, 1922]: “Party to seek rare mammals. Mexicans and Americans on exploration trip. Lower California is mecca of scientific party. Commissioner of fisheries in charge of work. San Diego, July 10. The Mexican fisheries guard boat Tecate, on which a party of Mexican and American scientists are to seek reported remnants of rare species of mammals in Lower California waters in the next few weeks, left San Diego yesterday. The Mexican government supplied the boat and subsistence for forty-five days for the party. The Tecate is under the general direction and supervision of Prof. Carlos Cuesta Terron, commissioner of fisheries, Mexico City, who has associated with him the following Mexican scientists: Prof. Jose M. Gallegos, mammalogist and botanist, and Luis G. Rubio, taxidermist of the natural history museum, Mexico City; Rodolpho Lasano, inspector of lighthouses, Ensenada, and Enrico Gonzales, inspector of fisheries, Tijuana. The American scientific staff of the expedition is composed of Dr. G Dallas Hanna, secretary of the committee on conservation of marine life of the Pacific and curator of the California Academy of Sciences, San Francisco; A. W. Anthony, member of the committee on conservation of marine life of the Pacific and curator of vertebrates in the San Diego Natural History Museum, Balboa Park; Joseph R. Slevin, assistant curator of herpetology, and Frank Tose, chief taxidermist of the museum of the California Academy of Sciences; P. S. Barnhart of the Scripps Institution for Biological Research, and Ernest Hinkley of the San Diego Natural History Museum, Balboa Park.”
