Mr. DE MOHRENSCHILDT. Her mother is not actually practicing but she is in charge of the Cystic Fibrosis Research Institute in Philadelphia, she is a trustee of Temple University. But her husband, Dr. Denton---- Mr. JENNER. She remarried? Mr. DE MOHRENSCHILDT. She remarried. Mr. JENNER. What is his full name? Mr. DE MOHRENSCHILDT. Dr. Robert Denton. He is the doctor who treated our children for cystic fibrosis. At present he is a professor of pediatrics and assistant professor of pediatrics at the University of Pennsylvania. Mr. JENNER. I don't want to go into the litigation. There was some litigation, was there not, between you and your former wife with respect to some trust? Mr. DE MOHRENSCHILDT. Trust fund. Mr. JENNER. Established for whom? Mr. DE MOHRENSCHILDT. Established for Sergei, for our son. Now, I had to contribute, according to the divorce, $125 a month for the support of the children, which I did, and she put that money in a trust fund. She did not want to use that money for the upkeep of the children, because she is independently wealthy, and eventually she refused to accept any more contribution of money from me. I objected on my side to the fact that I was removed away--that the children were very far away from me. They were living in Boston at the time, and I encountered constantly difficulties in regard to my visitation rights of the children. Well, anyway, finally all of a sudden, after Sergei died, a long time afterwards, I received a notification that we inherited, my ex-wife and I--we inherited this trust fund. Mr. JENNER. Which trust fund? Mr. DE MOHRENSCHILDT. Established for Sergei, our son. Mr. JENNER. Who established the trust fund? Mr. DE MOHRENSCHILDT. Her grandfather, my boy's grandfather, Mr. Sharples, plus the money that came from my monthly contribution for the children's support--whatever money she could put in it. Anyway, it was a small trust fund of $24,000, which eventually was split up between my ex-wife and myself--about $12,000 each. There was a litigation in regard to that, but I don't know if it is interesting for you. Mr. JENNER. No--I have the complaints. Your ex-wife--Dr. Denton lives in Philadelphia? Mr. DE MOHRENSCHILDT. Yes. Mr. JENNER. And she does research work, does she? Mr. DE MOHRENSCHILDT. She doesn't do the actual research. She is more or less running the administration end of a second foundation. She was eventually asked to leave the National Cystic Fibrosis Foundation which we had formed together in Dallas, and which became this national foundation.
