And, I taught in the Austin College in Sherman from—it was the fall of, yes, it was fall of 1961 and 1962. No—1962 and 1963. Now, I am teaching at SMU or Dallas College, to be specific, of SMU.
Mr. Jenner. Have you done any interpreting or translating?
Mr. Mamantov. Yes, sir; for the American Geophysical Union, quite extensively in 1959, 1960, and 1961, and I think—yes—1961 I finished.
Mr. Jenner. And have you also done any interpreting or translating for any law enforcement agencies?
Mr. Mamantov. Here in the States?
Mr. Jenner. Yes.
Mr. Mamantov. Let me think a little—no, I don't remember. I have translated minor papers, you see, like Soviet Union's marriage certificates and birth certificates for our local courts connected with divorces, and I might be of a help to a group of Latvians, people here in town, when they received their citizenship, so much, but this is the first time for the police department.
