Aside from his editorial work at Science, Boas secured an appointment as docent in anthropology at Clark University, in 1888. Boas was concerned about university president G. Stanley Hall's interference in his research, yet in 1889 he was appointed as the head of a newly created department of anthropology at Clark University. In the early 1890s, he went on a series of expeditions which were referred to as the Morris K. Jesup Expedition. The primary goal of these expeditions was to illuminate Asiatic-American relations.[35][36] In 1892 Boas, along with another member of the Clark faculty, resigned in protest of the alleged infringement by Hall on academic freedom.
