<p>It does happen at Harvard quite frequently. Undergrad/grad/professorhip. Often, as Professor X, without getting tenure. But, Jeffrey Sachs and Larry Summers were Harvard products all the way through, to take a couple of examples. There’s no presumption of weakness. I know lots of Harvard profs with Harvard doctoral degrees.</p>
<p>Although medical school faculty is different, you see lots of people with Harvard Medical School faculty appointments who are Harvard undergrad/Harvard MD. Similarly, at Harvard Law School, you’ll see Harvard undergrad/Harvard JD now on the faculty, although I think this is happening less frequently.</p>
<p>Perhaps a wee bit of institutional arrogance in evidence? But a lot of the people I’m thinking of are very strong.</p>
