Mr. JENNER. You were young and full of energy? Mr. DE MOHRENSCHILDT. While working for the Humble Oil Co. I said that a man without the education in that particular field--I did not have the background of geology or petroleum engineering, except that I kept on studying by myself. I didn't have much chance to succeed. I was wrong, by the way. I should have followed Mr. Blaffer's advice and gone in the oil business, and I would have been a multimillionaire today. Mr. JENNER. Well, you might still be. Mr. DE MOHRENSCHILDT. Well, I probably will be. But really that was--he was the man, the only man who gave me the right advice--of all my friends and acquaintances. He said, "George, go on your own and try to speculate on oil leases and drill wells on your own," which is the basis of the oil industry. "We will give you a lease, you can promote some money to drill on it, and here you have it." And that is what happened. That is the origin of many, many of my friends in Texas who are very wealthy. Mr. JENNER. All right. You came to Texas---- Mr. DE MOHRENSCHILDT. Came to Texas---- Mr. JENNER. 1944. Mr. DE MOHRENSCHILDT. Yes. Mr. JENNER. That was following your divorce from Dorothy Pierson? Mr. DE MOHRENSCHILDT. Yes. Got a loan. Mr. JENNER. You entered---- Mr. DE MOHRENSCHILDT. Entered the University of Texas, and School of Geology, and Petroleum Engineering as my minor--major in petroleum geology and minor in petroleum engineering. And with a fantastic effort and speed I succeeded in getting my master's degree in petroleum geology and minor in petroleum engineering in 1945, I think. Mr. JENNER. You received your master's in 1945, did you not? Mr. DE MOHRENSCHILDT. Yes. 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? Mr. DE MOHRENSCHILDT. In the fall of 1945. Mr. JENNER. How long were you at the University of Texas? Mr. DE MOHRENSCHILDT. I think about 2 years. Mr. JENNER. Now, following your obtaining your master's degree at the University of Texas, did you enter into business? Mr. DE MOHRENSCHILDT. No; I got a job waiting for me in Venezuela, the Pantepec Oil Co. in Venezuela. Mr. JENNER. What was the nature of that work? Mr. DE MOHRENSCHILDT. I worked as a field engineer. Mr. JENNER. In Venezuela?
