Mr. Jenner. And in petroleum geology?
Mr. De Mohrenschildt. Yes; with minor in petroleum engineering.
Mr. Jenner. Did you pursue your studies further?
Mr. De Mohrenschildt. No; well, I wrote a dissertation. I pursue my studies as the time goes by. But that was the end of my education in American schools.
Mr. Jenner. Now, while you were at the University of Texas, did you serve as an instructor——
Mr. De Mohrenschildt. In French.
Mr. Jenner. You had no tenure there? You were not a professor?
Mr. De Mohrenschildt. No; an instructor in French, to make some additional money.
Mr. Jenner. When did you complete your work at the University of Texas—all of your studies?
