In 1879 Peirce was appointed half-time lecturer in logic at the recently established Johns Hopkins University in Baltimore. He had been employed by the Coast Survey since 1861, had been appointed assistant by Benjamin in 1872, and would retain his position with the Survey while at the Johns Hopkins and until 1892. For reasons never fully clarified, in 1884 his tenure at the Johns Hopkins was terminated, and since then Peirce would never again have an academic position. 1
