Law of the United States
The success surrounding the publication of "Introduction to Municipal Law" earned him an LL.D degree from his "alma mater" and an appointment to University of New York City as a professor of Law, and later chair of political science in the undergraduate department. Pomeroy later served as dean of the recently established school until 1871. While teaching, he also wrote the treatise, "Introduction to the Constitutional Law of the United States", in 1868, which was the first legal text on constitutional law published after the Civil War.
