Professor Lerner went on to develop a theoretical model for an artificial heart pump which utilizes the bodys own endogenous materials for energy supply. It is viewed by the American medical community as a unique contribution to health science. In the fall of 1981. Professor Lerner was forced to stop his weekly seminars following serious threats from the KGB. In late 1982. Soviet authorities threatened his son with criminal prosecution and loss of Moscow residence rights if he persisted in meeting with Western scientists. As Professor Lerner enters the 70th year of his life. let us hope that Soviet authorities will grant him a long overdue exist visa. and that his wish to reunite with his family in Israel may finally be fulfilled..
