Birkett D. Fry, who entered West Point with the Class of 1846, but was dismissed from the Academy after failing mathematics and did not graduate. Source
John Waugh, The Class of 1846: From West Point to Appomattox. (New York: Ballantine Books, 1994).
bonus: Town: St. Johnsbury State: Vermont Company: E & T Fairbanks Company - the inventors of the first platform scale - (and the governor in 1861 - Erastus Fairbanks) was the "E" in E and T Fairbanks. The company is still in St. Johnsbury making scales. However, the original building that "temporarily" housed the "Official Standards of Weights and Measures of the Federal Government" was destroyed by a fire in 1972.
Edit - I'm still not sure how anybody was able to start a successful search for the answer to the main question unless a copy of Waugh's book fell off the bookshelf and landed open to a page where Birkett Fry was mentioned, but my congratulations to the eight players who correctly identified him.
