Pretty tough to do, since Princeton has no law school.
The Law School at the College of New Jersey (now Princeton University) was a department of Princeton University from 1847 until 1852. It began instruction in 1847 as a modest effort consisting of three professors: Joseph Coerten Hornblower, Richard Stockton Field, and James S. Green. Only seven students obtained a law degree before the school closed in 1852. The short-lived experiment was the furthest the university got in a recurring ambition, marked by varying levels of effort, to establish a law school. Previously, in the 1820s, an attempt was made to organize teaching in law, but this plan ended with the death of the designated professor. In 1935, the university once again formed appreciable plans for the start of a law school but was unable to secure a faculty. The desire remained after these unsuccessful efforts but aspirations were relegated to thirsting words rather than material preparations. In 1974, then president of Princeton, William G. Bowen, selected a committee to investigate and advise on the achievability of a law school. The committee recommended plans for a law school be deferred after citing high construction costs.

It was Harvard Law. Dershowitz was his law professor.
