Law school deans, deans of the medical school, some professors of finance and engineering. Probably not too many gender studies professors or even history professors.
If you want a world class medical school, one needs to pay competitive salaries. In the early 1970’s the dean of the medical school at the University of North Dakota in Grand Forks and the director of the state mental hospital in Jamestown both made more than the governor.
In the 1970s Governor of small states were not a big paying jobs. In Maine, Brennan took home 35K IIRC in his first win for governorship back in the late seventies.
