('68, A.M. '71, LL.D. '94) was associated with him in the Museum as Assistant Curator. In 1873 Winchell resigned to become the chancellor of Syracuse University and was succeeded by Eugene Woldemar Hilgard (Ph.D. Heidelberg '53, LL.D. Michigan '87), to whose professorship mineralogy was added in 1874.
Hilgard remained only two years, then resigned to accept a position in the University of California. Under him for the first time there appeared more than two names on the roster of the staff of the department. Mark Harrington was promoted to an assistant professorship, and there were two assistants in the Museum. Harrington's position at first was in geology, zoology, and botany, but in 1874 it was narrowed by the omission of geology. When Hilgard left in 1875 Harrington was put in charge of zoology and botany, and never again was geology (except as paleontology) included with biology as the appointed field of any one member of the faculty (see Part III: Department of Botany and Department of Geology ).
Joseph Beal Steere ('68, '70l, Ph.D. hon. '75) joined the department in 1876 as Assistant Professor of Paleontology and Curator of the Museum, and Volney Morgan Spalding ('73, Ph.D. Leipzig '94) came the same year as Instructor in Zoology and Botany. In 1879 zoology was separated from both botany and paleontology; Spalding's title was thereupon changed to Assistant Professor of Botany and Steere's to Professor of Zoology and Curator of the Museum; at the same time, Winchell returned to a chair of geology and paleontology. Thereafter, until 1885, only Steere's name and that of an assistant in the Museum appeared in connection with work in zoology.
In that year Howard Ayers joined the staff of the Department of Zoology for one year. He was succeeded by Jacob Ellsworth Reighard ('82, Sc.D. hon. '36), who continued many years. Others who were added to the faculty with the rank of instructor or higher were the following: Frederic Leonard Washburn (Harvard '82), 1887-88; Louis Murbach ('89, B.S.[Bio.] '90, Ph.D. Leipzig '94), 1891-93; Henry Baldwin Ward (Williams '85, Ph.D. Harvard '92, Sc.D. Cincinnati '20), 1892-93; and Dean Conant Worcester ('89, Sc.D. hon. '14), 1893-98.
Steere resigned in 1894, and Reighard, who had become Professor of Animal Morphology in 1892, took charge of the department. In 1895 he was officially designated as Professor of Zoology and Director of the Zoological Laboratory and Museum, and he continued as head of the Department of Zoology until 1925. Of the many new members added to the faculty of the department in this period, those who held the rank of instructor or higher included the following: Charles Atwood Kofoid (Oberlin '90, Sc.D. hon. ibid. '15, Ph.D. Harvard '94), 1894-95; Frank Rattray Lillie (Toronto '91, Ph.D. Chicago '94), 1894-99; John Black Johnston ('93, Ph.D. '99), 1897-99; Fanny Elizabeth Langdon ('96, M.S. '97), 1898-99; Herbert Spencer Jennings ('93, Ph.D. Harvard '96), 1899-1903; Samuel Jackson Holmes (California '93, Ph.D. Chicago '97), 1899-1905; Karl Wilhelm Genthe (Ph.D. Leipzig '97), 1899-1901; Raymond Pearl (Dartmouth '99, Sc.D. ibid. '19, Ph.D. Michigan '02), 1902-6; James Edwin Duerden (Ph.D. Johns Hopkins '00), 1903-5; Dana Brackenridge Casteel (Allegheny '99, Ph.D. Pennsylvania '03), 1905-9; Otto Charles Glaser (Johns Hopkins '00, Ph.D. ibid. '04), 1905-18; Horatio Hackett Newman (McMaster [Toronto] '96, Sc.D. ibid. '33, Ph.D. Chicago '05), 1905-8; Arthur Sperry Pearse (Nebraska '00, Ph.D. Harvard '08), 1908-11; Robert William Hegner (Chicago '03, Ph.D. Wisconsin '08), 1908-17; J. Frank Daniel, 1909-10; Peter Olaus Okkelberg
