Mr. MAMANTOV. No; my wife still was in Roswell, N. Mex., at that time and she moved to Dallas immediately after the Thanksgiving Day. Mr. JENNER. In 1955? Mr. MAMANTOV. Right. You see, we received our citizenship in November of 1955 at Roswell, N. Mex. Mr. JENNER. Both you and your wife? Mr. MAMANTOV. Whole family, and Mrs. Gravitis. Mr. JENNER. Does that include Mrs. Gravitis? Mr. MAMANTOV. That's correct. Mr. JENNER. Any particular reason why you were in Roswell, N. Mex. Mr. MAMANTOV. I was with Donnally Geophysical Co. at that time. Mr. JENNER. And was its main office located there? Mr. MAMANTOV. No; this was the field party. The office is located here in Dallas and we traveled--at the start of 1951--Post, Tex.; Brownfield, Tex.; Lubbock, Tex.; Hobbs, N. Mex.; Odessa, Tex.; Roswell, N. Mex., and I left---- Mr. JENNER. I think that's enough. Mr. MAMANTOV. My family and my wife and I moved to Mississippi for a month. Mr. JENNER. Still employed by Lion? Mr. MAMANTOV. Still employed by the seising crew which was in Magee, Miss. From there we moved to Palacious, Tex. From there to Coalgate, Okla.; from Coalgate, Okla., to Seminole, Tex. My wife quit the company at that time and went to Roswell to join the family. Mr. JENNER. Is your wife a professional person also? Mr. MAMANTOV. She is not graduated from a law school, but she went quite a way. Mr. JENNER. She took legal training, training in the law? Mr. MAMANTOV. Right, but she worked as a geologist--as geological computer for that particular company. Mr. JENNER. Did she finish her law work in Europe or here? Mr. MAMANTOV. No; she didn't graduate. The Communists moved in and our law didn't exist at that time, as well you know. Mr. JENNER. For the purpose of the record, I am Albert E. Jenner, and this gentleman is Jim Liebeler. We are members of the advisory staff of the general counsel of the President's Assassination Commission, and under the provisions of Executive Order 11130, dated November 29, 1963, Joint Resolution of Congress 137, and rules procedure adopted by the Commission in conformance with the Executive order and the joint resolution, we have been authorized to take the sworn deposition of Mr. Mamantov. I should also say to you, Mr. Mamantov--have you had 3-days' notice? Mr. MAMANTOV. Yes, the Secret Service called me on Friday and on Saturday I received your letter, which was sent to my old address. Mr. JENNER. Well, that might not be technically 3-days' notice. You are entitled under the rules of procedure to the 3-days' notice of the taking of your deposition. Mr. MAMANTOV. Yes; Friday, Saturday, Sunday--I had. Mr. JENNER. You are entitled to waive that full 3 days if you desire, and do you agree to waive it? Mr. MAMANTOV. I mean--I agree to deposition--I don't know your legal terms. Mr. JENNER. We've got you into Dallas, now.
