An international authority and legal expert on world press freedom and telecommunications policy will address Brigham Young University students Oct. 13 as part of the department of communications' symposium series.

Leonard Marks, a Washington, D.C., attorney who was director of the U.S. Information Agency for four years and is legal counsel for the World Press Freedom Committee, will speak at 11 a.m. in the Par-doe Theatre of the Harris Fine Arts Center.He will discuss the United Nations' Declaration of Human Rights calling for the free flow of information, along with the current state of press controls in various parts of the world, including the Soviet Union and other Eastern European countries.

Marks returned last week from Moscow, where he negotiated with Soviet officials over international broadcasting.

"It is very possible that Leonard Marks has had more influence on international telecommunications policy than any other person," said M. Dallas Burnett, professor of communications and coordinator of the speaking series. "He has advised four of the past six American presidents on these issues."

Marks was appointed incorporator of the Communications Satellite Corporation by President John F. Kennedy in 1963. He was chairman of the U.S. delegation to international conferences on communications satellites in 1969 and 1970, an appointment made initially by President Lyndon Johnson.

President Richard Nixon named Marks as chairman of an advisory Commission on International Education and Cultural Affairs from 1974 to 1978.

In 1983-84 and 1986-87, Marks served by appointment by President Reagan as chairman of the U.S. Delegation to the International Conference on High Frequency Broadcasting.

Marks has practiced law in Washington, D.C., since 1939. While in Utah he will also address the Inter-American Press Association annual convention, which is being held in Salt Lake City.
