William R. Day,
Watson v. Maryland — Opinion of the Court
“ There is perhaps no profession more properly open to such regulation than that which embraces the practitioners of medicine. Dealing, as its followers do, with the lives and health of the people, and requiring for its successful practice general education and technical skill, as well as good character, it is obviously one of those vocations where the power of the state may be exerted to see that only properly qualified persons shall undertake its responsible and difficult duties. ”
