Mr. DE MOHRENSCHILDT. Yes; then Lehman Trading Corp. in New York. I may have had other jobs, but they escape me now. But they were all consulting jobs for clients of mine--either from Texas or from New York. And then in 1957 those foreign jobs led to my being pretty well known in that field. I was contacted by Core Lab in Dallas in regard to a job in Yugoslavia. Mr. JENNER. Tell us about that. That was for---- Mr. DE MOHRENSCHILDT. That was for ICA--a job for ICA and for the Yugoslav Government. Mr. JENNER. Tell us what ICA is. Mr. DE MOHRENSCHILDT. International Cooperation Administration here in Washington--which wanted an oil and gas specialist to go to Yugoslavia and help them develop oil resources under the--I don't know--some kind of government deal. Under this---- Mr. JENNER. Did a man named Charles Mitchell accompany you? Mr. DE MOHRENSCHILDT. Yes--George Mitchell. Mr. JENNER. And his wife? Mr. DE MOHRENSCHILDT. Yes; I found him because he was a geophysicist. In other words, I did the geology and petroleum engineering, and he did pure geophysics. The ICA needed two men. I looked over the country for somebody who was capable and willing to go to Yugoslavia, and found George Mitchell in Dallas, and eventually both of us went there. Mr. JENNER. You were single at this time? Mr. DE MOHRENSCHILDT. Yes. Mr. JENNER. And he was married? Mr. DE MOHRENSCHILDT. He was married. Mr. JENNER. And his wife accompanied him? Mr. DE MOHRENSCHILDT. She did; yes. Mr. JENNER. This was for the International Cooperation Administration? Mr. DE MOHRENSCHILDT. Washington 25, D.C. The Yugoslavian Government paid my living expenses there, and the ICA paid my salary. Mr. JENNER. And you had a contract of some kind? Mr. DE MOHRENSCHILDT. Yes; I think the contract was for 8 or 9 months. Mr. JENNER. Now, you left on that venture, as I recall it, somewhere around February of 1957, wasn't it? Mr. DE MOHRENSCHILDT. I left for Yugoslavia. Mr. JENNER. Yes; you left for Yugoslavia when? Mr. DE MOHRENSCHILDT. I think it was very early in 1957, because, 8 months, and I returned in October. Mr. JENNER. 1957? Mr. DE MOHRENSCHILDT. 1957; yes. All the reports were made--quite a considerable number of reports were made in triplicates--some of them went to ICA, some went to the Yugoslavian Government. I think some went to the Bureau of Mines here. Mr. JENNER. That was nonsecurity work, was it not? Mr. DE MOHRENSCHILDT. I don't have the slightest idea. They checked me, they gave me some kind of clearance before I went there. Because I had to wait for quite some time before they gave me the okay. And I noticed that after I got back from Yugoslavia, they were still checking me--after I got back from Yugoslavia they were still checking on me. One character came to see some of my friends in Dallas and said, "Well, George De Mohrenschildt is about to go to Yugoslavia. Do you think he is all right?" He said, "But he is already back from Yugoslavia."
