National Museum of Natural History (U.S.). Dept. of Invertebrate Zoology.

The Department of Invertebrate Zoology was created in 1965 by the separation of the Department of Zoology into vertebrate and invertebrate branches. The Divisions of Marine Invertebrates and Mollusks were under administrative control of the newly created Department of Invertebrate Zoology. On July 1, 1965, the Division of Marine Invertebrates was abolished and three new divisions were formed--Crustacea, Echinoderms, and Worms--and were joined with the existing Department of Mollusks to form the Department of Invertebrate Zoology.

Chairmen of the Department of Invertebrate Zoology have included Donald Fleming Squires, 1965-1966; Joseph Rosewater, Acting Chairman, 1966; Raymond B. Manning, 1967-1971; David L. Pawson, 1971-1975; W. Duane Hope, 1975-1981; Clyde F. E. Roper, 1981-1985; Roger F. Cressey, 1985-1988; C.W.
