Bell achieved prominence as an attorney very quickly, and he was noted for his corporate work. He was offered a judgeship, but declined. When in 1902 sitting Philadelphia District Attorney John Weaver won election as the city's mayor, Bell accepted the appointment to take his place, and then ran for and won a term on his own, but declined a renomination. As District Attorney, he was noted for enforcement of food purity laws. He gave the annual address before the Law Academy of Philadelphia:
The Several Modes of Instituting Criminal Proceedings in Pennsylvania. An Address...before the Law Academy of Philadelphia, May 27, 1904. (Philadelphia, Dukes, 1904) that gave a useful detailed discussion of how a person might be indicted for criminal proceedings in early twentieth-century Philadelphia. In 1911, Governor
John K. Tener appointed Bell as state Attorney General. Upon completing his term, Bell returned to private practice. Bell died of heart disease at his home in Philadelphia on December 29, 1935. ==Notes==
