Mr. DE MOHRENSCHILDT. Yes; Col. Edward J. Walz, this was my wife's uncle, Miss Sharples' uncle--much younger than his--than her mother, but a man of substance, from Philadelphia--with whom we developed friendly relationship. He liked me and I liked him. And we decided to form a partnership, and we called this partnership Waldem Oil Co.--with the idea of doing the same thing I did with Ed Hooker--that I would do the fieldwork and he would do, more or less, the financial end of the business in Philadelphia. We had several very successful dealings together. On our first drilling venture we found oil. I kept producing that little field for quite some time. Mr. JENNER. What field? Mr. DE MOHRENSCHILDT. Post field, in Texas--a small part of this field belonged to us, and we kept on producing. We did other operations in the oil business, selling leases, buying leases, and things like that. But we didn't do anything spectacular because he never could provide any large amounts of money for anything spectacular. We did small things. It was a small operation. But we always made money together. Eventually, after my wife and I got divorced---- Mr. JENNER. Now, you mention divorce. You and Wynne Sharples were divorced? Mr. DE MOHRENSCHILDT. Yes. Mr. JENNER. And when did that take place? Mr. DE MOHRENSCHILDT. That, I think, was in 1957, I guess, or 1956. We were married for 5 years. Mr. JENNER. Well, it must have been 1957, then. Mr. DE MOHRENSCHILDT. 1957, yes; it turned out to be that both of our children had cystic fibrosis--it is a terrible illness of genetic nature. The children who have it have no hope to recover, as yet. Now, my ex-wife and I started a foundation, National Foundation for Cystic Fibrosis in Dallas, of which Jacqueline Kennedy was the honorary chairman. Now, my ex-wife says that I didn't have much to do with this foundation, this Cystic Fibrosis Foundation, but actually I did, because I collected most of the money from my Dallas friends. It started with very little--we started with $10,000 or $20,000, and now it is a $2 million foundation, with headquarters in New York. Last year I was chairman of this foundation in Dallas for the first public subscription to our Cystic Fibrosis Fund for the Dallas children, and we got $25,000. Now my son, Sergei, died from cystic fibrosis in 1960. By the way, the reason for our divorce, in addition to whatever disagreements we had, which was not very important, was the fact that we both obviously have a tendency for cystic fibrosis, a genetic affinity for cystic fibrosis, and the children born from such a marriage have a very poor chance to survive. She wanted more children. She was scared to have more children with cystic fibrosis. The little girl is still alive. She lives in Philadelphia. Mr. JENNER. She is with her mother? Mr. DE MOHRENSCHILDT. With her mother, yes. Mr. JENNER. Is her mother pursuing her profession in Philadelphia?
